Has anyone tried Mobil 1 fully synthetic with their hybrid truck, I am debating on whether or not to use 0W-30 or 5W-30 Mobil 1 fully synthetic?
I heard you might be able to squeeze a little more mpg with the 0W-30.

 

I recommend 5w30.

M1 is a great oil.

getting better mileage with 0w50 is a weird thought since both oils at operational temp will behave as a 30 weight.

It might give better starting in super cold weather and a 5 minutes better flow than the 5w30. Just my opinion.

 

Hmmm perhaps more research is needed.

Check this link out from mobil

Most engine wear occurs at start up. Lighter is better, especially in cold climates.

 

Been running 5w-30 from almost day one. Change the oil out every 6000 miles. No problems yet.

 

What ever oil you use just make sure it's good oil.

Or here's the thread i started here sometime ago about the same thing as above. It's pretty much a copy and paste of the above link.

After researching, I went to wal-mart & the 0w-30 m1 is the same price & on the bottle it says that it has better cold starting protection & here in northern texas the temps are below freezing at night & early morning. I will update when I do the change & whether or not I notice anything especially in mpg increases.

 

I have used 5w/30 mobil 1 extended performance since break-in oil and noticed a longer intervals of at least 10k miles in between oil changes and it still has a lot of base stock oil after 10k miles as per my blackstone tests. it has also been certified as a dexos 1 oil. it is oem requirement for my escalade hybrid.

 

oil is one of the cheapest investments you can make in car maint. I change mine every 3k ( a bit obsessive i know) also I change ALL fluids in all my cars regardless of mileage every 2 years. (typically 20k miles for an 2 year period) I took the 08 yukon in last year and they told me I was being excessive but it really pays you back. I do EVERY liquid inc. brake fluid, PS fluid, trans, diff, oil antifreeze....basically everything liquid. Brake fluid is hydro-scopic IOW it absorbs moisture naturally so after 2 years I figure it needs a change.

 

that is why I am using the 5w/30 mobil 1 extended performance(fully synthetic) and use the MM to change oil.
