Part number for the oil: G055512A2 $14 (x2) O-ring: N90362001 $4 (x2) Paid ~$38 total Yeah my dealer is about 40 minutes away so I bought two in case I want to order oil in the future and do this again sometime...or if it leaks for some reason and I have to drain/refill, I just didn't want to drive back.
Put 100k miles on my mark iv jetta tdi while using the stuff. No problems.
I use Mazda's weight recommendation for my environment, as illustrated in your owners manual. I use 10W-30 and 15W-40 Full-Synthetic oils with zinc additives to stave off carbon deposits.
From my personal experience, I used to use Mobil 1 and Pennzoil Ultra Platinum oils, which are really high-quality oils. However, I did notice a big difference when I began using the OEM Mazda oil. I don't know what is so different about it, but my engine runs much more smoothly and very quietly. When I am at a stop light, I don't even feel the engine running, it's gotten that quiet, and I just hit over 100k miles.
I use Mazda Moly 0w-20 in our 2014 Skyactiv CX-5.
The oil spec for the 1.8L engine in my 2019 Golf Sportwagen S 4motion is 502.00 (5W40). After my last oil change at the dealer I questioned whether they used the correct oil because the service ticket was written up wrong. The dealer supplied these photos to show how the different grades of oil are actually different colors. The oil on my dipstick was caramel colored, so I knew it was the correct grade for my car after all.
That PN is listed as genuine Volkswagen oil for your vehicle. You’re all good!
For the record, this is NOT the exact replacement to Mazda 0W-20 GF-5 with Moly - Synthetic Engine Oil.
While this has high molybdenum, it's still a different formula from Mazda's own proprietary blend.
Well, just got back the test results on for our oil analysis, here are the comments: " Nothing showed up in this sample that's too much of a surprise, though aluminum and copper are perhaps a little higher than expected. New parts wearing in tend to leave a lot of metal in the oil and that's what we suspect is going on here. You ran this oil pretty long for factory oil (we realize you were probably only following the oil life monitor). So that's why aluminum and copper are on the high side. No matter--everything should improve now that you've changed this fill. The TBN read 1.9, getting low but still okay. Potassium is from the EGR system. "
My Mk4 Golf is at 146000. And I've religiously changed oil and filter every 4000. One time I let this synthetic oil go for 9000 miles, it caused pre-ignition and destroyed 2 sparkplugs, needed a tow, and a expensive sparkplug replace at VW.
