If you're on a budget, don't drive your car or sell it for something you can afford that takes regular gas.

To play devils advocate, the Nissan Altima with a KA24DE runs on 89 octane, the Nissan 240sx with the same KA24DE recommends premium only. I always ran my S14 on 89 and it never had a problem.

Not the case here. Different engine, different tuning. It would almost be better if he was using regular only. When you run premium, the ecu advances timing up to the knock threshold. When you switch to regular, it knocks until the ecu pulls that timing back. If he ran regular only, it wouldn't keep going through the advance, knock, retard cycle going back and forth between octane. That's not a recommendation to use regular, just that what he's doing is the worst of both worlds.

Just use the right damn gas, people. If the $3 difference per tank is the deal breaker, sell the car or buy $3 less of premium.

No joke! I mean its $3!!! WTF That is almost the price of a soft drink inside the gas station. Just ride your bicycle and give up now.
