Can you run lower octane fuel in your dodge stealth rt 1995?

Answer 1

As long as it doesn't "ping" severly Pinging is pinging and no amount is acceptable. In some instances you can run a lower octane fuel than is required by the manufacture but at a price. If the fuel/air management and timing are computer controlled, then the computer may adjust for the lower octane fuel. Not sure about your model year. This will cause a loss of power and lower MPG. So, you may in the end spend more for fuel and have less power. Sometimes this pinging or pre-detonation may be so slight as to not be audible. Pinging is never a good thing and will eventually cause damage. For this reason, never, ever, run a lower octane than is required. Your car requires Premium Unleaded. That may mean 89 or may mean 91 octane. Check your owners manual for the requirement. You bought a car with a high compression engine that requires the use of premium fuel. You knew this going in, so bite the bullet and only use premium fuel or suffer the consequences. Another choice is to sell this car and buy one that can burn regular unleaded.
