On Toyota's Canadian website it recommends using Toyota full synthestic 5w30 oil in the new 4Runner.

Is this the same here in the US?

I was always tought that its better to use fossil oil for the first 2 oil changes, and then switch to synthetic.

What is your opinion?

 

I think Toyota is right on this but I think I'd use Mobil-1 intead of the Toyota oil. They don't make it in any case.

I've changed vehicles with as little as 1000 miles over to Mobil-1 with no problems. It's factory fill on a number of new vehicles now so there must not be a breakin problem.

I would use fossil oil for the first 5000 miles then use synthetic oil if you want.

 

Amsoil suggested I use standard motor oil until the first scheduled oil change (5K) for my 2003 Highlander. I thought the Toyota US FAQs recommended the same.

 

My Tacoma has Synthetic Mobile 1 5-30 in the engine and has Amsoil series 2000 75-90 in all the diff. and transfer, next is the Automatic transmission has any body used mobile1 in there transmission? amsoil will cost 150 $ just for the 15 quarts of ATF I was thinking Mobile1 is somewhat cheaper.

 

well, amsoil told me i could use synthetics from day one.!! like it was stated earlier-you are good to go. alot of new cars come with synthetics from the factory.
