I have a fortuner 2.7V. It will be 4 years old middle of this year.

I've always used 91 benzene (kaaw nung thammadaa).

I've noticed that getting 91 benzene is getting more and more difficult. PTT rarely seem to have it - only 91 gasahol. I drove back along Rama II road last year in to BKK, the fuel gauge was showing very low, and i think it was the 6th petrol station i went in to before i found 91 benzene. That was an extreme situation, but i often find petrol stations don't stock it or they have run out of it.

91 benzene is also very expensive compared to 95 benzene and 91 & 95 gasohols.

So, what fuels can i put in to the fortuner 2.7V without detrimental effects?

I have a 2.7 Fortuner too.. The dealer told me that 95 is fine as well as Gasohol91..

The car drives fine too on 95.

am sure the truck would run fine on 91 gasohol. Just go for it.

I would also install an NGV system if I was you to save on fuel expenses.

Gasohol 91 or gasohol 95 is fine.
