Thread: Premium or regular gas?

I run only 92+ in the Volvo. Power in this sucker is great. The torque, HA. It's awesome.

stock says it runs on regular. I run regular, but I am thinking of advancing timing soon so that might change http://www.fueleconomy.gov/feg/findacar.htm

ROFL love how the Least Fuel Efficient Passenger Cars are like Lambos and Bentleys

Holy hell, 6 city 10 highway for a 1986 Lamborghini Countach.

you're in el cajon? how far are you from JWT?

sorry for the threadjack!

This has been covered quite a bit hehe.

OK the Higher Octane is better fuel Myth.

If you are NA and are at stock timing, if your running anything but 87 your wasting your money. In fact if you run higher octane fuel you will probably see worse gas mileage!

All Octane ratting means is, resistance to burn under pressure. So 87 gas actually burns better and easier then 93. The only reason you would need 93 gas if you have a performance engine that has higher compression or bumped timing, in that case higher octane fuel lets the piston to go up all the way and not detonate.

WOW, you just saved me all that typing thanks.

As covert said that is what it is, NOTHING ELSE.
You need to understand were your going with this.

93 for better Gas Mileage or better for your motor?

BTW, gas from a mom and pops store or from Ammaco BP, Exxon.. you getting the SAME SH!T. BELIEVE ME!!
My brother in law that drive a BP Gas truck delivers to BP, Exxon and all the mom and pop gas stations on the SAME TANKER.

Besides, its a frickn' sentra.. you do WAY WORSE things to that car racing it boosting Modding then anything you could EVER in your life put into that gas tank from a pumping station.

P.S. Stop advancing your timing. It's no longer considered a Mod. Pay top dollar gas price for a 1hp gain?????? LMFAO.

^^ Glad to save you some time

Now 93 gas is usually known to have more detergents, so thats what makes it more expensive. Who knows if those detergents are helping your engine or making it worse though

About a 5 minute drive, I would say at least 4 miles away.

I run only premium 93 on my Boosted B14 and 91 on the G35.

latley ive been seeing on the pump contains 10% or less ethleen .
