It is always okay to switch between regular and premium gasoline. With that said, it depends highly on the make of your engine whether or not your car will actually benefit at all from the use of premium gasoline. Make sure to look in your car's manual before you switch to see if your car can benefit for from the switch.
i am guessing you should use premium gas for a Chrysler 300. Regular is ok unless you have a SRT8.
Yeah it shouldnt hurt anything
Yes, all gas powered motors can burn premium. Some engines don't run well on regular.
Yes. Any vehicle that can run premium gasoline can run on regular. With that said, if your engine is such that it can benefit from premium gasoline, it will lose some of its performance.Sure. All cars are designed to run on the lowest grade. only use the others if you really need extra Octane (engine knock)if your car requires premium gas, then that' what it needs. If you try to run it on regular it might start to knock, spike and run poorly. This may even damage the engine.If you really feel the urge to experiment, you can put some regular gas in and see what happens.Start with 1/4 of regular and 3/4 of premium.If it runs OK on that, even on hard acceleration, try 1/2 premium, 1/2 regular.If it runs OK on that, even on hard acceleration, try 1/4 of premium and 3/4 of regular.If it runs OK on that, even on hard acceleration, try all regular.
Try regular 87 Octane - if it does not "ping" excessively you should be OK - if it does "ping" excessively try 89 octane
Premium is ok
For a real answer check out this http://www.cartalk.com/content/features/premium/questions.html Their answer is a qualified yes, it is OK to use regular in modern cars. But read the all the details in the link above.
you will be ok MIGHT notice a very s;ight decrease in performance
Most small engines are designed to run on regular unleaded gasoline; the higher octane premium gasoline may eventually be harmful to the engine.
yes its ok to run premium in it but when i ran it really didnt see any difference
I run standard gas in my 1995 4.0 and it runs fine. If you notice a pinging noise upon hard acceleration go back to premium. But you should be ok.
Unless it calls for premium gas in your owners manual your wasting your money using premium.
