What grade gas do you use and where do you pump your gas at?

OK... My salesman recommended I use 91 octane gas instead of regular gas.... Is this necessary? Anyone else using a higher octane gas? Where do most of you fill up at? Shell, Exxon, etc...?

 

I use what the owners manual recommends. Does it call for 91?

I buy the cheapest gas I can find, like Sam's, Costco, Speedway, Racetrac.

I've done this for hundreds of thousands of miles over many marquees, including high revving sports cars and muscle cars, with no ill effect.

Running a higher octane than the vehicle was engineered for only lightens your wallet. It won't run better, faster, get more mpg or do anything to 'clean' the engine.

 

I use regular (87) at Costco.

 

87 and 89 so far.

 

Top Tier fuel is what you want to use. Octane rating isn't as important.

 

He's right. I work for a gas station company and we have an environmental guy who tests our tanks.

Some of us also test other companies at the pump in our personal vehicles. You'd be surprised at what you find.

 

I've been pumping 87 octane at Speedway... I'm told to stay away from BP Stations due to excess amount of additives... True?

 

Ask whoever told you for documentation.

Then buy the lowest price around and enjoy your truck.

I've never focused on using 'top tier' fuel, and never had a fuel related issue. But then again, I've never kept a vehicle longer than 200k. So maybe not long enough for a problem to show up?

 

They do have a lot of additives and ethical.

 

I thought the "additives" is what was supposed to make their gas better?

 

I mistakenly put 89 in a vehicle that required 91. Ever since then. I put 93 in all my vehicles.

Also. What's a bp station so I can stay away from it.

 

This gives a new meaning to the phrase 'paying for past mistakes'

 

DI motors have an issue with carbon buildup on the underside of the valves. Top Tier fuels supposedly have a cleaner and more complete burn.

 

BP stands for British Petroleum

 

Wasn't this a thread yesterday?

 

Higher octane means it has a higher resistance to burning, meaning its designed for high compression engines that will "detonate" with low octane fuel. An engine designed to run 87 will not gain any performance from running a higher octane fuel. As said above, you want to go with a "top tier" fuel if you're willing to spend the extra green. I always go with either Chevron or Shell regular octane. Occasionally Mobil if there's no Chevron around.

Costco is Top Tier fuel as are most major name retailers -- keep in mind there are sub-retailers under this list. For instance Safeway or Von's Gas stations could be supplied fuel from a Top Tier Supplier.

 

Thanks for the input Styx586

 

Costco Regular!

 

Sam's Club or QuikTrip
