Mazda MX-5: Miata Maintenance Day

Great day to work on the Miata this Memorial Day weekend. Sunny, 90 degrees… too hot to put the top down but quite pleasant in the shade. Bill stopped by for an oil change and to try running Mobil 1 high mileage 5w30 in his car, which I may do myself in the future.

Glad to see everything nice and clean on Bills car since the last time we did an oil change. One thing that stopped working though was the LED license plate bulbs that we replaced last July. Mine also burned last winter so I ordered some new ones. As soon as we plugged it in Bills car it started flickering, so we decided to go to the store and get a traditional non LED bulbs… which are surprisingly expensive at $5/ bux a pair.

Lickily the Walmart we went to had some Mad Mike ND Miatas in the toy aisle…so I bought every one they had. Will be since gift to someone someday.

Mazda MX-5: Oil Change Deal Castrol EDGE + K&N Wrench-Off Filter $22.99

Memorial Day oil change deal alert at your local Advance Auto Parts store… while I’m not due for an oil change and I still have a perfectly good jug of Castrol EDGE 5W20 from a previous purchase, along with a bunch K&N HP-1002 and PS-1002 filters for my Miata, at this price I decided to stock up on a few more.

The deal is $22.99+ tax for a 5QT Jug or 5x 1QT bottles of Castrol EDGE full synthetic oil plus a K&N Wrench-Off high performance oil filter… which at Advance Auto typically sells for $36.99 just the oil and $16.99 just the filter. Of course I like to shop around and have purchased oil and filters cheaper individually but in this case the combination of the two work really well, I’ll explain why.

Advance Auto is currently running a promo through American Express also, where you get $10 rebate on your AMEX card for a $50 purchase. Similarly, Advance Auto SpeedPerks rewards program allows you to earn $5 (coupon you can apply to a future $20 purcahse) for each $30 you spend. Naturally the $22.99 deal is after rebate, so the $32.99 you shell out upfront qualifies for this deal.

The Castrol EDGE Extended Performance oil is also on sale, a 5QT jug of that is $24.99 after rebate with the K&N filter included. So what I did was purchase both, sending my total with tax to $70… I quickly got an e-mail confirming my AMEX rebate. I’m hoping SpeedPerks comes through for at least $5 maybe even $10 since I spent over $60 (2x – $30) and in the end it will be a fantastic deal.

Almost as good as those end of fiscal year clearance sales where Advance Auto or AutoZone clear out their oil supply and sell 5QT Jugs of various oils for like $5 bux. But alas those deals are hit or miss and sometimes only apply for specific oils. For example two years ago I managed to buy Mobil 1 for $5 a jug, except it was only the 0W20 weight. I read about Pennzoil Platinum going on sale for a similar price but out of the three oils I have used in the Miata, the Castrol EDGE goes on sale least. And I found out it’s the oil that performs best in my car, yielding the best gas mileage!

So I’ll stick with it for a while.

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.

Seeing the RX-8 up close and personal made me appreciate that car a bit more, it’s surprising how massive it is compared to the Miata

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.

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.
