my Chrysler 300 was acting up, stalling, shaking. I started using the more expensive gas and it got better.?

Question

Has anyone else run into this?

Answer 1

First, you should never run an octane less than what the owner's manual calls for - this gasoline can ignite too early when the piston is still coming up, which can produce anything from shaking to noise to severe engine damage. I've seen several cases of cars having pinging or preignition trouble when running on the wrong octane.

Also, I haven't had it happen to one of my own cars, but I've heard of a lot of cars that were picky eaters and refused to run correctly on a particular brand of gas. Some discount gas companies do cut a few corners that they can usually get away with - but for some reason a few engines don't like the corners they've cut and run badly on it.

Answer 3

Well I agree with sprinkels. However there is something you need to know. Most premium gasolines contain additives for cleaning the injectors. (something Chrysler cars don't have a lot of problems with) Premium fuels go farther on mileage, but the extra price cancels out that advantage. Also premium gas with the added cleaners, has a tendency to build up deposits in the combustion chamber caused by the additives. The very stuff that cleans the injectors, will also leave deposits when burned.
Oh, and do like the rest say and get a tune up. They advertise 100,000 miles between tune up. Don't believe it. 50,000 miles is long enough before tune up.

Answer 4

No, Gamer. What i will wager is occurring is which you p.c.. somewhat greater gasoline in to the tank while the nozzle kicks off. which will tension gasoline up into the vapor traces and into the charcoal canisters. Then once you're taking off, somewhat of purging extra fumes out of the canisters, you're drawing out uncooked gasoline into the intake manifold and into the cylinders. the suited way, and this is on your proprietor's handbook to boot, is to no longer placed any further gasoline interior the tank while the nozzle kicks off. That way you will no longer flood the vapor canister device with uncooked gasoline. And the gasoline tension alter isn't defective and that's a ingredient of the gasoline pump.

Answer 5

they all get like that when they need tuned up,it might be a good idea to at least have it checked,if it does need a tune up using more expensive gas in it wont cure the problem it will just hide it for a while,that one should actually run pretty good on regular,good luck on it.

Answer 6

EVERYDAY....CARBON BUILD UP FROM USING THE CHEAPEST GAS.

TRY USING A PRODUCT CALLED BG-44K AND ADD IT TO A FULL TANK OF SUPER UNLEADED GAS AND RUN IT TO SEE IF IT WILL CLEAR UP THE PROBLEM AND IF NOT.................

I WOULD RECOMMEND THAT YOU GET YOUR VEHICLES COMPUTER SCANNED TO FIND OUT JUST WHAT THE PROBLEM IS FIRST SO THEN YOU WILL HAVE SOME IDEA WHAT IS WRONG AS WELL AS WHAT TO EXPECT.

TRY FINDING AN INDEPENDENT AUTOMOTIVE REPAIR SHOP INSTEAD OF THE DEALER OR ANY CHAIN STORE BECAUSE YOU WILL BE OVERALL MORE PLEASED WITH THE PERSONAL SERVICE THAT YOU WILL RECEIVE.

Answer 7

Your car probably needs a tune up. Do that and you can do back to the recommended fuel. Don't go below recommended though. That would cause problems long term too.

Answer 8

my chrysler book says, the engine runs better if you use high octane gas, I don't know, if this is true , because I cant afford it.

Answer 9

Yeah mine was doing the same thing...except mine was transmission problems (torque converter)...I'm so tired of this car! It has only 17,000 miles on it and it's been to the shop 4 times for engine and transmission problems...I will never buy a Chrysler again!! I should have stuck to foreign...LOL!

Answer 10

it depends on what engine you have. the 3.5 has had problems with exhaust valves carboning up and not sealing from poor fuel and lack of driving them hard. there are revised valve keepers that help the valves rotate and not build up carbon.
