Oil - GR 0w-20 is thicker than mobil1 0w-20

[Noctb48MD]

I have been topping off the oil in my car for three years with Mobil1, 0-20 and this weekend I went to buy new spark plugs and saw on the shelf the "GR!1!" bottles available. The parts guy said the GR stuff is thicker, and then my supra mechanic said oof, use liquimoly. Why tf would toyota do this? Or does this shit not even matter.

Both oils are 0W-20 they are of the same viscosity. Just up to you on which one you can afford and which one provides better quality to your engine

This thread is useless without centipoise.

Here's something to consider; the U.S. service manual says to use 0w20 and 0w30, while the Japanese service manual says you can use 0w20, 0w30, 0w40, 5w20, 5w30, and 5w40.

Does it matter? I mean, probably to someone.

In the words of my buddy "as far as weights go, 0w vs 5w is a little thicker, my dad was putting 20w50 in his Chevelle, thats some heavy *** oil compared to 0w20/5w20/0w30/5w30".

I ultimately ended up going with 5w30. If my motor blows up, I'll let y'all know! Can always yolo it and send it off to Blackstone for analysis.

Im pretty sure 5w40 is thicker than 0w20 I could be wrong

I use to buy those small BMW bottles, but I started using LiquiMoly in 5L and not going back. I like big jugs.

Toyota’s standard 0W-20 synthetic oil and the GR 0W-20 oil for the GR Supra are not exactly the same. The GR 0W-20 oil is specifically formulated for high-performance engines like the one in the GR Supra. It typically includes additional additives to enhance performance under more demanding conditions, such as higher temperatures and pressures.
