Owner reviews for engine oil

I have a 2015 Tacoma 4-cylinder stick shift 52,000 mi. I bought it new. The only maintenance I had to do was oil changes and I go underneath with a grease gun and grease all the fittings along the axle.

Castrol EDGE Euro is also VW 508 spec.

I just use LiquiMoly 0W-20 with the VW spec

The mechanic is absolutely wrong. You must use a 5W-40 C3 oil with the Fiat 9.55535-S2 specification, I use the Castrol Magnatec 5W-40 C3, which is cheap and easy to find, but any other brand with the correct specification is fine. A 0W-20 oil has insufficient pressure and film strength, and will lead to damage over time.

From personal experience I have always changed oil every 3500-5k miles depending on how I drove. I used to do 6500-7500k and I noticed on my 540i last winter on days when it got below 20 degrees the engine was very noisy during the first 5-10 mins driving. It was so noisy I was convinced it was piston slap or something. It wasn't a low oil "thunking" sound though. Always kept it under 3k rpms and was very gentle on those cold mornings. This was when my oil had 4-5k+ miles on it and it was last changed in Sept 2024 and this was Jan 2025 back then. So I scheduled an oil change worried my oil was low or something and the noise went away. Oil quantity came out normal no burn or leak! After that I reduced my intervals to 5k max and I also always changed the oil before winter/summer (mid-late Oct and early-mid April) ever since following this personal guideline of mine I have never experienced that cold rough engine sound in the winter anymore. Also two examples of manufacturer oil recommendation being shite is the B58 states 0w-20 but the manual says 0w-30 is acceptable. I also noticed that switching to 0w30 the engine sounded/felt smoother especially on cold idle. Second example is N63tu2 BMW used to recommend 5w-30 but then they dropped it down to 0w-30. Many cases of those motors particularly found in 2018 M550i's etc were consuming 1qt every 3k-4k+ miles yikes! But once switching back to the original 5w-30 recommendation all consumption ceased.

The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.

262k miles here on an M54B30 with 10k changes, Mobil 1, it's running great.

I’m up to 150k miles on my B58. Oil changes every 10k miles from new. Still running smoothly, not burning any oil, pretty sure it’ll go another 50k miles at least. Personally, through 5 BMWs, I’ve always just stuck with the factory recommendation and never had the slightest issue. It’s always been the rest of the car which has gone before the engine.

I googled today to see if the STP Euro synthetic oil was 502 00 and the answer came back as - should be but to actually be able to put 502 00 on the bottle companies have to pay for it to be certified and STP probably just doesn\u2019t want to pay.

0W-20 at 5K interval. 74k miles.

Gen 1 B58 with plastic oil pump. Increasing oil viscosity is a recipe for failure, especially in cold climate.
