Ask a question and you get a million answers. Bought the 2015 Equus obviously I knew it was a V8. It would stand to reason such a engine would require Premium gas, yet I'm being told you can get away with regular. I've never heard of that in a V8. Why I ask this question is,my so called certified Hyundia Equus guy tells me so. But then I don't believe everything I hear. Clearly the full tank they gave me was garbage gas...I have since filled it up twice with premium and it's Purring again.BUT ! in a last minute pinch could I use regular gas "without" doing damage to my engine ?
