Anyone using a higher viscosity oil in their Tundra?

I appreciated it.

 

I'm gonna swap mine over to 5W-30 and then I'm gonna change the oil fill cap to a 5W-30 so it will be the correct oil technically, cuz that's what the fill cap says. Lol

 

I've been running Kirkland 5w-30 for the last 30k with 5k changes. On sale it's $3/qt and well reviewed on BITOG. The Mobile 1 5w-30 sheared down to 0w-20 after 5k FYI.

 

Just imagine what 0w20 becomes after 5k miles. Even worse at 10k.

 

-5w10. It flows backwards in cold temps.

Yes, I know there are multiple fallacies in that joke.

Oil is not thinner at cooler temps.

 

Strong argument for running 5w30.

 

Yah if I knew what I do now when I bought I would have run 5w-30 from the 500 mile mark.

 

First oil change in the Tundra surprised me. Really looked like water when I pulled that drain plug.
That was after 500 miles no less. Keep that in for the first 10k? No thanks Toyota

 

just my .02, but I think the 0w20 is fine but no longer that 5K intervals.

thats what Im doing anyways.

 

Better question becomes.... does the 0w20 really save on gas vs. 5w30 ?????????????????

 

I doubt anything significant. I got 21.5 on my last road trip segment, 170 miles, freeway and primary highways. This fill was 5 qts 5w-30 and 2.7 qts 0w-30. Now maybe if I did the same exact trip with the 0w-20 it would get a tenth or 2 better... but, of course, there really is no way to duplicate any given trip, traffic and weather conditions.

 

Immaterial for us. Material for Toyota under the CAFE act.

 

5w-30 just feels right.
