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 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.

Mazda MX-5: Oil Change at 5,000 miles with Mobil 1 Synthetic 0W-20 & M1-102 filter

File this one under the: “what have you done to your Miata today” category. I changed my oil. It was exactly 5,000 miles since the last service in April, at 37,297 miles which included several 400-500+ mile road trips Upstate New York to Watkins Glen and New England to Thompson Speedway. In fact my father and I changed the oil on both the old Ford Explorer SUV and the Miata, and I mention the Explorer for a reason, because I want to use a different oil the next time I do my service, one that doesn’t turn so dark so quickly.

I got a hell of a deal December of last year when walking into a local AutoZone I found a 5-QT jug of Mobil 1 on sale for $5. I bought two. This is the second jug being used. I was reading all about Mobil 1 on Miata.net, and so many people swear by it, but I don’t see what the big deal is, especially when you consider paying the full price which is typically around $27 to $35 depending on the store. The oil turned dark at only 5k miles, about the same shade of dark as the Explorer’s standard Pennzoil 10W-40 at 4k miles, and it’s not synthetic. The feel is about the same on the Miata as on the Explorer. Maybe I had unreasonable expectations for the feel from the Mobil 1.

Mobil 1 Advanced Fuel Economy “Recommended for most Hondas and Toyotas”

But at any rate I think I’ll try something else in the spring time to at least make a comparison for myself. I will stick with 0W-20 weight and full synthetic, but will change the brand.

The options are:

Pennzoil Platinum or Ultra Platinum

pennzoil platinum 0w-20 or ultra platinum 5w-20

Castrol EDGE or Castrol EDGE Extended Performance

castrol edge 0w-20 or castrol edge extended performance 5w-20

I’m also thinking of replacing the Mobil 1 M1-102 oil filter with a K&N version, which seems like it’d be easier to install and remove when the time comes with the wrench instead of trying to work in a tight space the way it is now. The nut seems like a great idea. The filter goes for around $10 to $15 apiece, available at Walmart but probably the most reasonably priced at Moss Miata – $9.95

So if anyone has any personal experience with the products I’ve listed above or some other products that I haven’t considered, like for example the $37 a jug Royal Purple synthetic oil, do share your thoughts… please! I would especially be interested to hear from people with a NC Miata so I can base my decisions on something concrete. A real world experience, like I got from Jason for example, Stevie – his 2009 Miata gets Pennzoil Platinum + K&N filter changed on an 8,000 mile interval. That’s impressive!

Oh yes, besides the recommendations on facebook and Miata.net I am a sucker for Motorsport advertising, hence the BFGoodrich tires for my Miata just like the BFGoodrich sponsored MX-5 Cup series cars (tires might be different but whatever). So which cars use what oil in what series? Well, this Mazda comes to mind using Castrol:

Mazda MX-5: Oil Change, Wheel Swap, Miata Meet

Today was a good day to work on the car. So for the first time in my life I went ahead and changed the oil in a car: my Miata. As with anything else that I’ve done to this car so far,  it took unnecessarily long. What seemed like hours. But everything was done right.

miata oil change mx5

I followed the recommendations from Miata.net and acquired some Mobil 1 0W-20 fully synthetic oil… yes the oil cap on the engine says 5W-20 and no – that’s not what I went with. I got what most people agree is the best option for the car. And I used a Mobil 1 M1-102 oil filter too, because… why not?

The funny story behind the oil is that I got it dirt cheap from a local parts store. How cheap?

mobil 1 price mistake

$5 dollar cheap… that’s a hefty discount considering Wal Mart sells the jug for $36 dollars. I randomly stumbled upon this deal and couldn’t believe my eyes. Was totally convinced it was a price mistake, asked the clerk if they would honor an obvious price mistake, but the item scanned at $5 bux. So I bought two jugs. Now I know it says 0W-30 and posting this picture on the forums resulted in comments that people would gladly use it for that price. But after about a month from the purchase I went back to the store and they happily exchanged my two jugs for the correct oil. So all was good. I bought the oil filters on Amazon for $10 bux each, or double what I paid for the oil, how ironic?

I took the opportunity while doing the oil change to thoroughly clean everything under the car including the oil pan protection plate which was covered in grime. I also noticed that a few plastic clips were missing in the shroud that surrounds the front wheels so I popped some new ones in place. Car fired up and purred like a kitten after the oil change. Drove nicely. Although when sitting at a red light the engine RPM’s drop a lot and I wonder if it’s normal.

I also took the opportunity to try out my newly purchased 16″ OEM wheels. I noticed that on the road trip I scuffed the front 17″ OEM wheels up a little so it was time to try something softer and smoother for our pot-hole infested roads. And boy did they make a difference. Granted the feeling is identical with larger pot holes, but the general crap you encounter on the main highways like the New Jersey Turnpike or the Garden State Parkway is manageable. And the difference is obvious. I am liking the softer ride. I really don’t think I understand how people lower their cars and get fancy big wheels with low profile tires. It must be solely for the looks. They must not drive their car much. Or they must really like doing wheel alignment from hitting pot holes so hard their teeth chatter with a stiff suspension.

miata wheels

I am a big fan of the 5 spoke wheels, though the 10 spoke ones will go back on the car in the summer time when roads are better.

The fella I purchased the wheels from invited me to a Miata Meet his club was organizing. So as soon as I finished tinkering with the car and took a quick shower, I hit the road for Central Jersey. This month the Delaware Valley Miata Club was meeting in Freehold, NJ at Jersey Freeze burger and ice cream shop. They do this sort of thing monthly, and the mid-week afternoon event totally works for me since I can’t get off from work on the weekends. There were about twelve (12) Miatas present of which 1 NA, 3 NB’s, 4 NC1’s, 3 NC2’s and 1 NC3. It was very cool to see other Miata owners from New Jersey and Pennsylvania, especially the guy with another Copper Red Mica. I was eager to compare the rear bumpers to see if the shades are off like they are on mine. But by the time I noticed his car it was too dark outside for a good comparison. Still a nice feeling to see another similar Miata so close.

Great crowd and very good food too.

So all in all what  a beautiful day! I got to change my own oil. Change the wheels. See how the car feels with the new oil and the new wheels on a 140 mile road trip. And meet a dozen other Mazda Miata owners in New Jersey over a delicious dinner. Looking forward to more of this in the summer time!

Note to self: oil change done at 32,295 miles… when should the next one be? 5,000 miles? 10,000 miles?
