« on: Sunday,September 19, 2021, 10:06:35 AM »
I found this guys blog and spent way too much time reading it.

What I got out of it was Quaker State Full Synthetic 5W-30 is hard to beat unless you need a high temp oil the It's Castrol GTX or Pennzoil Ultra Platinum Full Synthetic 5W-30

Sadly, full synthetic also means leaks unless you just assembled the engine with synthetic in mind.
Tried it, did not like it.

He covers cst, actual viscosity at operating temp, 212F. Some aren't as thin for the given weight. There's a lot of data in there.

 We only run Synthetic. My only light leaker, 98' Frontier has 325k on it. All our Toyota's are 120,160, 245k and not a drop.
