Engine oil Mobil or AMSOIL

Mobil 1 Advanced 15w50 automotive oil. Yes you heard me right. No it doesn’t cause clutch to slip. $25 for 5 quarts at Walmart. Best protection against friction and wear money can buy. 11k and zero issues. No metal shavings on drain plug after break in with factory oil.

Audi uses Mobil 1 at the dealer level. Stick with that.

I've been using Mobil 1 0w30 in my NA 2018 CX5 for 180,000 miles , no issues and runs quieter than 0w20 .

My daughter has a 2016 Civic bought new. First oil change was at 200mi with Mobil1 Extended, and then oil/filter changes at 15,000 or 20,000 mile intervals until 86,500. Switched to Restore and Protect and after 1k miles I changed the filter and cut it open, there were zero sludge deposits, and oil color looked new.

My T/A 392 has seen 311°F. ????. I added a bigger oil cooler after that.

I was running 0w40 Amsoil Signature, no metal in the filter.

I'm fairly sure Mobil1 makes the Toyota branded oil, which is what I'm running in my 2023 Hatchback XSE. I'm using the Toyota 0W8. I also plan on keeping my car for as long as the wheels turn.

I'm a loyal Amsoil user. I usually change my oil every 5k miles. However, 3 oil changes ago, I started sending samples to Blackstone.

First Analysis: paraphrased, engine looks great

Second Analysis 5k miles later: Engine Looks great, Oil still has plenty of life

Third Analysis, another 5k miles later: everything looks great, try waiting 8k between oil changes.

Exactly. Change the oil pressure switch. I would spend $50 and get an oil pressure test set with gauge and check pressure to be sure. Oil must be synthetic that meets proper spec. 5w-40 mobil1 European does.

Throughout the summer I was averaging a quart every 750-1000 miles, still using Mobil1 15w50 & Viscoplus. This winter it dropped back down to 1 quart every 500 miles, but as the weather has warmed up, my consumption seems to have decreased again. I think that had something to do with the oil, which was admittedly way too thick for cold weather. I would let the car warm up a couple minutes before driving because that oil is syrup in cold weather.

personally, I think Amsoil AFL is junk. They ruined a stout oil when they reformulated it to mimick 505.01.
