Support Motorsport Sponsors?

This post is about motor oil and the holiday season shopping, shall we say- opportunities? Yes! It’s all about great deals on products from companies that support Motorsports through their sponsorship. I don’t know about others but when it comes to effectiveness of Motorsport advertising, I’m a sucker for buying things that are promoted on race cars. In this case it is Castrol EDGE motor oil for my Miata. I think I actually bought too much!

A little back story… I have been posting a lot of Miata.net about what oil is recommended for our MX-5’s. The answer is – surprising! People say it doesn’t really matter what you use in the car as long as it is changed regularly because most modern oils sold in the US right now are “good” and therefore no one is better than the other. That said many on the forums use Mobil 1 in their cars. And Mobil 1 sponsors quite a lot of Motorsport. So like sheep I went ahead and bought two 5QT jugs within the first year of ownership of my car and that is what I used. Until I became puzzled by the dark/black look of that oil when I changed it at 5,000 mile intervals. It did not seem right to me especially since Mobil 1 advertised the oil is good until up to 15,000 miles. Yikes!

The two Mobil 1 5QT’s that I bought were mysteriously priced low, at just $5 a jug… which is ridiculous. Normally the price is $25 at Walmart and $35 everywhere else from AutoZone to Advance Auto Parts. My alternative to Mobil in the second year of ownership turned out to be even cheaper to source. I decided to go with Pennzoil Platinum because again Pennzoil sponsored a lot of racing, some people on the forums swore by it (although there weren’t too many of those people, not nearly as much as Mobil 1 evangelists) and it was fairly cheap! Regularly priced at $25 to $30 from Walmart to the parts stores, but constantly on sale and with promotions from both Pennzoil and other sources that at some point cost me as low as $4 for a 5QT jug or in one case, I basically was paid to take the 5QT jug from the store after all the promos and rebates. (Pennzoil is famous for it’s $10 rebate or rather $2 per QT rebate up to $48 per calendar year, which is a lot of jugs). In 2016 I used Pennzoil Platinum exclusively. I liked it so much that I even got the Pennzoil Platinum High Mileage ATF for my JWS-3309 Aisin Transmission. Mostly 5W-20 felt amazing during the spring, summer and fall months. But using 0W-20 in the winter made the engine sound louder, which really perplexed me. I bought another 5W-20 jug to use later but also started considering alternatives, and now decided to start sourcing Castrol EDGE to try next.

There is a post I made two years ago after my last Mobil 1 oil change that I was contemplating trying Pennzoil Platinum and Castrol EDGE, and sharing that plan in a post created a goal which I am now going to meet. In 2017 I will run Castrol EDGE exclusively in my car and I’ve already sourced enough oil for 3 oil changes which is basically the 15,000 miles I plan to do in the coming year. I decided to go with the 5W-20 weight standard black bottle and not the gold extended performance bottle since I am only daily driving the car and not tracking it or using it in any kind of extreme situations. I do plan to make several trips to Florida which will rack the mileage up quickly, but also probably won’t require me to make as frequent changes as short trips in New Jersey would require with stop and go traffic, cold weather, etc. I am very much looking forward to giving this oil a go, and seeing how I like it compared to Mobil 1 and Pennzoil Platinum I already used. So far the standard has been set pretty high, but I have heard nothing but good things about Castrol and they are one of the big sponsors of the IMSA Mazda Prototype program which makes me feel like I’m supporting it directly now.

Price wise though I think the retailer is losing money selling me the oil because I’ve been taking advantage extensively of the Sears/Kmart ShopYourWay rewards program. Every time they sent me 5,000, 6,000 or 10,000 in points (where 1,000 points = $1) I immediately redeem them for another 1QT bottle or 5QT jug of the Castrol EDGE oil which they have in stock. Regular price for the 1QT bottle is $7.99+ tax. (Which seems ridiculous) Last one I bought with the 6,000 surprise point redemption only cost me $0.87 cents. Before that I redeemed 10,000 points and $5.50 for two bottles. The 5QT jugs which Kmart sells for $37 regular price I paid about $7 bux out of pocket after purchasing it in store on sale for $22.99+ tax, and redeeming some regular points and 4,000 surprise points. All in all an oil change will cost me under $10 for the oil and another $9 for the K&N HP-1002 filter which I sourced from Walmart. The good part about the four K&N filters I bought they were still Made in USA and not the newer style which are made in Korea (and for some reason people are complaining that their quality has dropped).

Now all I got to do is keep driving more so I can use up the oil quickly. 2017 is going to be an awesome year…

I should mention some of the other companies I support by using their products thanks to all the Motorsport advertising I’ve been exposed to:

  • BFGoodrich tires – I have two sets, one summer one winter
  • Sunoco Ultra 93 fuel – official fuel of NASCAR & IndyCar
  • BP 93 Ultimate – I know they sponsor loads of Rally racing
  • Mobil 1 lubricants in rear end, power steering, etc.
  • K&N oil and air filters, also official sponsor of NASCAR
  • Bilstein shocks – huge sponsor especially during Nurburgring 24h

I’m sure there’s more that I’ve used or will use in the future.

For those of you that support Motorsport sponsors in your shopping – kudos to that! If you don’t, and use the argument – why pay more when there are cheaper options? Well, as I’ve demonstrated above, it is possible to use brand name and pay less, way less. You just need to shop around… for me it’s a challenge that I enjoy! I especially like buying branded gift cards, like those from BP, ExxonMobil or Sunoco with 5% to 10% discount for each dollar spend, making my expensive Sunoco Ultra 93 fuel (which is typically more than a no name brand) a bit cheaper… considering fuel is about $2.60/gal at the moment, I’m paying 26 cents less a gallon, which brings the price right down to a low-cost option, and I’m buying a better product! That makes me feel good.

Mazda MX-5: Oil Change at 5,000 miles with Pennzoil Platinum 0W20 and K&N Filter HP-1002

Update: (Feb 2017) I wasn’t sure what was causing the car to act weird after this maintenance session at Chris’s house. Now that some time and mileage have passed I think I figured it out. And the result is a few issues. 1). part of the problem was the fact we overfilled the transmission fluid during the flush. There was an issue we found with proper checking of the level (which required running the car to get it warm, and then opening the check valve). 2). my car doesn’t seem to like 0W20 weight oil. I posted a few times that I don’t like Mobil 1 and now I can add Pennzoil Platinum 0W20 to the list. Both Mobil 1 and Pennzoil Platinum 0W20 turned real dark at just about 5k miles which shouldn’t happen. This makes me believe I should totally stick to 5W20 from now on. I’ve changed out the Pennzoil from this post with Castrol EDGE 5W20 and car feels absolutely perfect!


I don’t think I’ve ever had an oil change party with friends until this weekend, where my buddy Chris with a 2008 Silver NC1 GT PRHT offered to help me flush most of the fluids on my car while performing the same service on a bunch of cars in his household.

The plan was to flush the power steering fluid and fill it fresh with Mobil 1 ATF. Flush the Automatic transmission fluid with Pennzoil Platinum High Mileage ATF, and finally change my oil with Pennzoil Platinum 0W20 that I’ve had sitting at my home since about this time last year when I got the crazy deal from Advance Auto on two sets of oils (one 5W20 which I used up during spring, followed by two more Pennzoil Platinum 5W20 changes that I bought during the summer and now for the winter decided to go with thinner 0W20).

I’ll make separate posts for each maintenance item, so click on whatever interests you most:

I must admit that after doing all these fluid changes the car feels a bit weird and I can’t really pin point what the issue is. I’m sure it is fluid related because there’s a faint drone coming from either the engine or the transmission. Note to self: next time do one fluid flush at a time so if there is an issue like this it is easier to narrow down.

But back to the oil change party at Chris’s house.

The day started with a trip to the Subaru dealership to pick up an oil filter for his XV… then Chris changed his ’08 NC’s oil using Castrol Edge 5W20 Extended which I’d like to try in my car at some point in the future once Pennzoil stops being so cheap with all of their promos. While Chris’s brother Eric did an oil change on his Mazda RX-8 Rotary with Castrol Edge 10W30.

My car was last and oil was basically the last thing we did to it, but since it was the easiest job I’ll write about it first.

I was curious to see how Chris does his oil changes and for someone so meticulous as he is, he does it very differently than I do. He jacks the front, keeps the oil cap on, undoes the drain plug, the filter, and re-installs the drain plug with a new bolt that I picked up at a local Mazda dealer for $7.99 accompanied with a $1.65 crush washer. In all the oil changes I’ve done to my car to date I never changed the nut and the washer, but since Chris was doing my car for me, I had him do the same thing he does to his car, so mine also received the new bolt and crush washer. I typically jack the car up and put it on jack stands and when the fluid drains, I lower the passenger side so more of the dirty oil comes out. Chris doesn’t do that himself, which I found to be pretty interesting. Chris was surprised that his car took more Castrol Edge oil than it normally does using Mobil 1 oil which he has used in the past. Mine took the standard amount of Pennzoil that I typically use, which is just above 4.5 QT.

It felt good to finish up the day with the easiest job of the evening, the oil change… (which happened around midnight… Yikes!)

Now if only I could figure out why is my engine running louder on 0W20 compared to 5W20 and why there’s this faint shimmy going on that I could feel at highway speed which seems to come from the front of the car, around the engine area. (or possible the trans).

Mazda MX-5: Oil Change at 5,000 Miles with Pennzoil Platinum 5W-20 and K&N HP-1002 Filter

I’ve been looking forward to replacing my Mobil 1 synthetic with something different. This season I will be trying Pennzoil Platinum to see how it wears in my Miata. I bought two jugs last time there was a good deal on this product, a 5W-20 weight and a 0W-20 weight that I plan on using for the winter season. The deal came with a K&N HP-1002 oil filter that has a few neat features: 1). the top of the filter is nicely sealed in plastic so no crap finds its way in there while it’s in the box and 2). it has a convenient spot on the bottom for a wrench to slide in and tighten or un-tighten it which makes a world of difference in a tight space where the MX-5 has it’s oil filter.

The oil change has been done at 42,459 miles which is 5,162 miles since the last one and just a week since my 3k mile road trip to Florida. I was not terribly surprised to see how dark the Mobil 1 synthetic got after just 5k miles. They advertise extended range performance of 10k and even up to 15k miles, but I wouldn’t use it much longer than my 5k. I noticed after draining the old oil to return it to Advance Auto Parts for disposal, there were a bunch of tiny metal shavings at the bottom of the pan. That’s not very nice to see. And finally, I must be good at draining all the oil out of the engine because when I refill the car with new oil and crank it up I get a little sound of a knock before the oil spreads through the engine properly. I’ve been following my dad’s advice to false start it a few times for the oil pump to spread the oil, but obviously the few false cranks I did weren’t enough. That had me a little nervous about damaging the engine by hearing that noise which happened for a fraction of a second, but long enough for me to hear it.

Hopefully the next oil change will be around October time at the end of the year so I can put the Pennzoil 0W-20 for winter use and not keep this oil much longer than I’ve had it already.

Mazda MX-5: Oil Change Deal! Pennzoil Platinum + K&N Filter $22.99

This post may be useful to a very small subset of readers, geographically located near an Advance Auto Parts store in the US with a requirement to purchase Pennzoil Platinum 0W-20 or 5W-20 fully synthetic engine oil and a K&N HP-1002 oil filter for cheap.

pennzoil

Less than 100 miles since my last oil change I came across this nice deal from Pennzoil and Advance Auto Parts. While Walmart generally sells the same Pennzoil Platinum oil for $22.99 every day of the week, with this deal you get a $9.99-$13.99 K&N filter for free… of course you pay $32.99 upfront and get a $10 Pennzoil rebate in the mail. Walmart isn’t participating in the rebate or this deal would have been even sweeter. The regular price for this oil is $36.99 at Advance Auto and other auto stores like AutoZone or PepBoys. I’m looking forward to giving it a try sometime next year. This combo came highly recommended by Jason who says he changes Stevie’s oil every 8,000 miles. Sounds good to me! Certainly better than the 5,000 miles I got out of Mobil 1 fully synthetic and the M1-102 Mobil 1 oil filter.

hello stevie 10 mx-5 miata

PS. I got two sets of the oil and filters. One set Pennzoil Platinum 0W-20 which is the same weight that I currently use with Mobil 1, and one set Pennzoil Platinum 5W-20 which is what is listed on the oil cap of the car (this was changed to 0W-20 in newer model NC’s). I want to see if there’s any difference in using one oil over the other. All in due time of course.
