Hi I'm planning to buy an 02 V6 Galant ES. Has anybody here ever tried putting regular gas on a V6 Galant? Is this possible? Thanks

 

Unless it's forced induced or is a high compression motor, regular (87-89) is usually what is recommended. The 6g72 & 3 (N/A) are neither of those, so regular is what's on the speedo. So, you should be good to go.
...and welcome to the board.

 

It should be ok but it will accect the preformance a bit.Also if it starts to ping alot I would go back to premium.

 

If the manual says premium, put that in.

 

Thanks so much for all your replies. Unfortunately the 02 Galant I was eying got sold already, I got an 01 Galant with 100k mi instead.

My svt called for premium but ran just fine on regular.

 

How the **** do you know?

Scientifically it will NOT run fine. Do I have to explain for the 500000000000th time?

Okay lets do it.

Gasoline has an octane rating, right? Basically the higher the octane, the slower the rate of combustion.

Pistons have a compression ratio, where they compress one volume of air, down to another. The higher the volume you compress, the more unstable the air/fuel mixture becomes. So, if you are running a lower octane fuel, with higher compression ratio pistons, then you are reaching the point where the potential energy is reached by purely putting it under pressure. So what you get from that is pre ignition, where the fuel ignites too soon. Why is this bad? Well think about that one... if the piston is still rising to the top when the fuel is ignited, it is directing all that force into that piston and rod ten fold. The stress is massive like taking a jackhammer to your internals.This is why we use higher octane fuel with higher compression ratio pistons, so you don't get pre ignition and **** your **** up.

It pisses me off when people say "Oh it runs fine....." How the **** do you know? Do you have a data logger? The bottom line is ... YOU DONT KNOW, and science has the answer.

Don't be a fool, put the right gas in your ****ing car, and if you can't afford the right gas, then either don't drive itor sell it.

 

Dude relax, I know what your talking abt, yes your right you shouldnt run reg in a car that call prembut the car will compesate by backing off timing so what is affected really is perfomance. I personally could tell the difference driving it, the avg person might not.

 

The 6g72 in the 3G is N/A... still requires premium.
