Is it OK to have gas from different companies at the same in my tank?

Question

I dont buy gas from the same station every time, and some times if I my tank is half empty and I see a cheaper price I just stop and fill my tank eventhough its a different "brand"

Answer 1

Believe it or not most gas is the same. Some companies do add certain addatives, but they will not interact in any bad ways.  What you do need to look out for is water in the gas at stations with old outdated storage systems. I do what you do, I fill up where ever i can to save money. Just to be sure , every second or third tank full, throw in a bottle of HEET, it will allow any water in youre tank to mix with the fuel .

Answer 2

it doesn't matter where you put it in as long a its good fuel,any kind or brand will mix together real well other wise their would be a lot of very sick cars on the road ,just stay with a major brand or  a station that sells a lot of gas,this way you don get that many drugs in the gas,good luck.

Answer 3

I always go for the cheapest so I can not always tell who has supplied my fuel. I've yet to notice ant difference in performance. In fact unless you are driving a souped up vehicle you will not

Answer 4

I can't believe you did that. You're lucky your car still runs, and it should have blown up by now. Mixing different brands is very dangerous, and it is even illegal in some states. You need to check with your local authorities. You may be breaking the law. You may be able to get a waiver from the DMF (Department of Motor Fuels) to put a different brand of fuel in your car if you are in an emergency, but good luck, I tried once when my wife was in labor and I was almost out of gas. They made her give birth on the side of the road.

Answer 5

What do you think ppl do when they are on Vacation...put different brands in b/c they are going different places. So it's no big!

Answer 6

I think it would be okay why not ask your car?\

although I assume you mean gas for your car

not your oven

Answer 7

That sounds entirely fine. I think everyone does it hun. But as long as its the same type of gas. For example if you got premium at one place then filled up with regular unleaded...thats bad.

Answer 8

yes that's fine...

Answer 9

Gas is gas, as long as you don't put diesel in a gasoline car or vice versa, you are as good as good.

Answer 10

No problem.  The gas might be formulated slightly differently, but they'll still be compatible.

Answer 11

You should have no problems mixing brands.  The engine management computer can adjust to variations in fuel from information gathered from various sensors located under the hood.

What is more important is that you only use the octane rating specified by your vehicle manufacturer.  99% of the vehicles on the road require 87 octane fuel.  This is because of the relatively low compression ratio of the engine.  Only higher compression ratio engines (10.0 to 1 or higher) require premium 92 octane fuel.  This is to prevent detonation (engine knock) which can do internal damage to the engine.

There is no benefit of using 92 octane fuel in an engine that only requires 87 octane.  All you are doing is giving extra money to the oil companies.  I think they make enough already.
