On the gas lid it says to use premium gas, anyone try reg, gas if so how does
it run with it.

 

I've always been told by mechanics that I know that you can you the lowest test fuel that does not cause the motor to ping.

 

I haven't refilled yet, but that's what I've always heard.

 

I'd say go with what the vehicle calls for in specs. After all guys, you might want to consider that those engineers that your mechanics seem to know so much more than, spend billions on designing these rigs to run a certain way for peak performance and longevity/reliability.

But remember, it is your car and you can do whatever you want with it.

 

There is a post over at www.FJCruiserForums.com that has a TSB stating that 87 octane fuel is fine and the door sticker on the FJ's was incorrectly printed.

Here is the link to the post:

:bigclap: OK, make sense,

 

ive only used mid grade in mine , the one time i did use the high doller stuff i got lower gas milage , might have jsut been coincidence , but ever since then ive stayed away from it. i havent heard any pinging or performance issues.

imo if they say to use a certain type of gas you should...

 

i dont agree. my 4runner called for middle grade in the manual and ive only ever used regular and its perfectly fine

 

Well I didn't pay attention to the Premium requirement until recently. I was getting really crappy gas mileage and before you say it gas is gas. There are only three companies the make gas and the only difference is the additives.

Anyway I kicked up the extra $4 for the tank of premium and my gas mileage is where it should be according to the specs. I'm sticking with premium.
