2000 Cadillac Eldorado Q&A

2000 Cadillac Eldorado Question: Can I use regular fuel instead of premium ?

I have a 2000 Cadillac ElDorado w/ 105,000 miles. -
Answer 1
I think Cadillac called for 91 octane on that car the engine has a knock sensor and diminishes performance if it detects detonation due to lower octane fuel. Check your owner's hand book and or call your Cadillac dealer see what they advise. -
Answer 2
yes caddys 2000 and newer can run on regular gasoline the computer will adjust for it -
