Time once again to prove my ignorance.

What is the thicker oil and better suited to hot weather riding?

10W-30 or 5w-40

I'v been using Shell RotellaT 5W-40 and just put in the new Mobil 1 10W-30 and started second guessing myself with a 3500 mile ride coming up.

This site explains it very well

I just did the complete Hookers trip on Amsoil 0W40, and have never had slicker shifting 8)


Stick with the 5-40, IMO, if those are your only two choices.

Would that be full synth, semi synth, or standard grade?

I'm currently running 10w-30 mobile 1 synth and shifting sucks. :x

Amsoil fully synthetic 4 stroke oil. I think it's marketed for ATV's & 4 stroke dirt bikes.

I'll check wally world for some.

Just a side note: I've flogged many of my vehicles and have yet to see the oil drain as gold as the XX.

Just a note to all you 10-30 users, It's not called for in the manual unless the temp stays between 10 and 90 deg. F.

It gets warmer then that even here in PA.

Where were you and your precious little manual when I was in Walmart yesterday? :)

Thanks for the info Lads.

You should have just asked the walmart associate, haven't you learned anything yet? :P
