Didn't have any noticeable oil issues, but I switched to Red Line 5W30 anyway.

Liqui Moly 5w-30 because it has a proven record with turbo engines and works best for my climate.

I would have thought you'd go for something like 0W30 given that it can get to freezing temps around Seattle, but it's probably not a big deal.

The Supra only hits the streets on nice weather days. The rest of the time its in a climate controlled garage.

If it was my year round daily I would consider a 0w-30 grade for sure.

X2 on this stuff. Makes the engine idle more quietly. More suitable for higher temp areas.

Liquid molly 5W30 special tec all the way.
I am tune pushing 750 HP the engine is very quiet and very smooth on high boost.

Quaker State Full Synthetic 5W30.

Because it is the very best oil of 264 oils tested in a controlled torture test for wear protection under extreme conditions. Test includes coverage of high-PSI protection, and resistance to thermal degradation or shearing. His results correspond nicely with HTHS and viscosity ratings for oils, if available, provided in the data sheets for these products.

AFAIK this is the most rigorous and scientific head-to-head test of oil on the internet. As far as I'm concerned, everything else is just one dude's opinion. "it's what i use and it sounds okay" is not rigorous enough.

This stuff?! Walmart Quaker state oil for $17/5qt

That's the stuff. As far as objective and metrics-driven testing is concerned: it's currently the best oil on the planet for wear protection under intense conditions. Acknowledged that the test database doesn't have all the info or options I would like (e.g. Amsoil XLOQT-EA or LiquiMoly), but that feels academic.

I'm going to stick with Molly, but I think for anyone looking for great oil on a budget or in a pinch, that stuff does seem like a great choice.

Agree with everything you said except for the diminutive "on a budget" or "in a pinch" qualifiers. It's demonstrably incredible oil, it just happens to be inexpensive and widely available. A sadly rare combination.

Same.

I was kind of hoping LiquiMoly made a 0W-30 that was basically same spec and approvals as the 5W-30 you posted above, but doesn't look like it exists. Does anyone have a 0W-30 they recommend? The LiquiMoly 5W-30 is nice because it does have all the right specifications and BMW approvals (Longlife-01).

Maybe Redline 0W-30? https://www.redlineoil.com/0w30-motor-oil

Just ordered 7 qts of Amsoil Signature Series 0W30. I feel like Amsoil is the best oil money can buy.

You don't need a 0W for freezing temps, even a 15W is fine below 0C. 5W is perfectly fine for a daily in all normal climates, just don't go driving through the tundra at -40C.
