Four Wheel Logic

No, you shouldn’t run plain water instead of coolant except as a short emergency top-up, because it lacks freeze, boil, and corrosion protection.

Yes, you can put water in coolant briefly in an emergency, but long use needs the right antifreeze mix and the cleanest water you can get.

Yes, you can use unleaded 88 in most 2001-and-newer gasoline cars approved for E15, but older vehicles and small engines should avoid this fuel.

Yes, you can put premium gas in most cars that use regular, but it rarely adds power or life unless your engine is built for higher octane.

Yes, you can add motor oil to a warm engine, as long as it is switched off, has cooled a little, and you never top up during severe overheating.

Yes, most gasoline cars can run on ethanol free gas, as long as the octane and fuel type match what your owner’s manual recommends.

Yes, you can put Christmas lights on your car for display, but driving with them lit is often restricted by local vehicle lighting and safety rules.

Yes, most cars can run on 93 octane gas safely, but only engines designed for premium fuel gain clear power or knock protection from higher octane.

Yes, you can use 89 gas in most cars when it meets the octane in your owner’s manual, but avoid it if your engine needs premium fuel.

Yes, most 2001-and-newer gasoline cars can use 88 gas, but you should read the pump label and owner’s manual before filling a full tank.
