Owner reviews for engine oil

im still on liqui moly 10w60 gt1

I'm a fan of Liqui molly GT1.

I use Redline 10w60.

I’ve been running mobil delay esp 5w40 it’s been working well for me.

Rotella T5, up to 14k in between changes per oil analysis. Great oil, never had any issues.

Cummins uses Valvoline premium blue.

I've always put Mobil1 High Mileage in my 2013 Scion tC, IIRC Mobil1 is what Toyota uses at the factory. I had a heavy upper oil pan gasket leak that's largely stopped since switching to high mileage oil.

Finally ended up with Penzoil Plat. Can't tell a difference at all when the oil is fresh. Also engine never burned oil on Penz.

On my 1.8ts I usually change it when the motor blows up and has to be replaced. They used to last perpetually but builds have progressed to the "Yes it absolutely is going to grenade or window the block before 10k miles???? so really I only ever have to FILL oil 1 time???? I wish this was less true than it actually is. On the rest, (2.7tt and 4.2) 10k miles if you use good full synthetic oil and a nice filter

I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
