Engine oil Mobil or AMSOIL

I have used Amsoil for years and I change my oil every 15,000 to 20,000 miles.

5 qt jug of M1 and a wix filter runs me just under $30 for most vehicles, and the oil is better than the conventional bulk crap most oil changes places use.

if you buy oil from Walmart, 5qt of mobil 1 or similar is well under $30. i buy the Mazda OEM filter/washer combos in a pack of 5 for like $6 per filter. so my oil change is around $34 (plus $10 for a bottle of techron) and i know i didn’t fuck it up.

for my 2025 camry, I get a 5 qt bottle of mobile 1 0w8 for $28 at walmart and a oem filter for about 5 bucks from the dealer with the washer, so a change for $33 bucks total.

I've been using Mobil 1 European blend 0w - 40 full synthetic. It's done me good for well over a year now.

I get my oil from Sams for about $60 for 4 gallons. I use the Mobile Delvac and haven’t had any issues.

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

if you to go for the best oil and the most expensive ones, you can use liqui moli, valvoline, ams oil

i use amsoil saber when i have it but not at 100:1 I don't really care if the engineer says its fine.

DO NOT use Mobil1 0W40 in the 2.5. I tried it and well before the oil change time, the engine sounded like a diesel with all sorts of valve train rattle.
