Can i use regular gas instead of premium gas? Is is possible to convert your car from a premium gas to regular by mixing and slowly decreasing the amount of premium until your mix is completely regular without damaging the car? I have been told that it's possible as long as the manual says recommend instead of required.

Re: 2002 Acura RL Premium unleaded fuel question
Recommended is just that... a suggestion. most cars will run just fine on regular gas although you may notice a difference from using premium all the time. if you still have the owners manual it should tell you.

Your jeep has two engine options, one was a standard 4.7 V8 and the High Output V8. Below is the recommended octane fuel rating. Unleaded regular, 87 octane (R + M)/2 - Standard; Unleaded premium, 93 octane (R+M)/2 recommended - High Output Thank you for using fixya and be safe.
Regular unleaded. Cars are designed to run on specific types of fuel and the fuel rating has to do with the temperature that the fuel ignites. The timing for saturn sc2's is set to run on unleaded. Premium will get you worse gas mileage, lower horse power, and possibly do damage to the engine by igniting at the wrong point during the cycle of the engine. As it says in the owners manual and on the gas clap, use unleaded.
when you open the gas flap to put gas in it should say "unleaded fuel only" or " premium unleaded fuel only". If it says premium only use premium. If it just says unleaded then you can use normal unleaded gas. But some stations have a lower grade unleaded gas. Use 88 octane or better.
Fuel comes in different grades due to octane levels, the higher grade the higher octane, the higher price. If you have the owners manual or window sticker, you would see that the car was probably made to run on 87 octane (regular unleaded), I have been through the different octane levels for more than 30 years and I have decided that the cheapest runs as well as the most expensive. The higher octane will sometimes cause an engine to ping or rattle under acceleration, if this happens to yours go back to the cheap stuff and everything will be fine. That is my opinion, others may differ, but I run my BMW on the cheapest I can find and I still get 31 MPG hwy.
HI. i recommend using the premium in this vehicle. This will ensure optimal performance. The fuel system will accept the regular blend as well but, this is not what this vehicle was engineered for. the regular blends octane level is not sufficient for optimal acceleration and overall performance.
Well, of course premium is HIGHLY recommended, but it is not necessary.
You can use regular grade in your engine and it will not harm it at all. Modern engine management systems have knock sensors that detect lower grade fuel and make the necessary adjustments to your timing and fuel delivery systems. All you will notice is slightly slower acceleration and a slight drop in engine horsepower.
If the engine requiresPrem fuel I would use it, the problems of not using it are possible piston damage. decreased power and lower fuel economy, when regular is used the knock sensor pulls the timing back to reduce knocking, this i where the lower MPG comes in and power problems, if knock can not be eliminated then the pistons may be damaged. I have a Corvette that uses Prem fuel, if I run regular I loose 3 MPG, so the trade for lower cost fuel is cancelled out by the loss of MPG.
