Many of the good brands of gasoline have additives in the formula. I had a healthy dose of an additive make a check engine light go off. That's only once in over a million miles of driving.
Premium gas has additives, regular gas no. Injector cleaners remove build up on injectors, don't know why he tested spark plugs. I use sea foam, seems to work, my last car had no fuel problems after 21 years of use.
ALL grades of gasoline have the additives advertised, whether they be "top tier" or "Minimum." "Regular," "Mid-grade," and "Premium" refer to the fuel's OCTANE; NOT the additive content! The oil companies ALWAYS advertise the detergent qualities of their PREMIUM fuels to get you to spend more money on gas than you need to! If your car takes regular, spending the extra money on premium gets you nothing but less money in your pocket! regular gas is actually MORE volatile than premium, as it has a lower flash point.
My old truck takes the 'cheap stuff' (i.e. 87 octane). When a bottle of STP gas treatment is added to the tank, I do experience better mileage, especially on the highway. When my family used to go out on vacations, a couple of bottles were taken, every other fill-up was given a bottle of this. It helped some but not a huge amount.
The cost of premium today, better additives SHOULD be part of the cost. At 70 cents more a gallon it should be.
I use Sea Foam in my vehicles once or twice a year. One thing the "Motor Oil Geek" doesn't touch on is that a lot of vehicles have direct injection now. This means that the fuel is squirted right into the combustion chamber, BYPASSING THE INTAKE VALVES COMPLETELY. Fuel treatment will NOT clean the intake valves in these engines, as the fuel/air mixture never passes through the intake valves! And those intake valves WILL get coked up to the point of needing manual cleaning ($$$). ...Ask my kid about his VW Jetta... You need to shoot cleaner into the air intake to clean these. I use the Sea Foam Top Engine Cleaner for this. You shoot the stuff into the throttle body while the engine is running. Then you shut the engine off and let it sit for about fifteen minutes. Then you start the engine and drive the vehicle like a rental for a few miles ("spirited driving" is how it's described on the can) to blow out all the crap the Sea Foam loosened. You'll see allotta blue smoke when you're praying the cleaner in and when you first start the vehicle after letting it sit. This is the CARBON and DEPOSITS the Sea Foam knocked loose! This stuff DOES WORK!!!

DeleteOccasional use can help limit carbon build up. But it's not the miracle cure the manufacturer's would have you believe.

ReplyDeleteI'll second the Sea Foam.
ReplyDeleteThat shit is awesome for cleaning both the combustion chambers with the valves and fuel injectors.
As an aside, premium gas burns hotter than regular gas. It does you no good if you don’t need it especially in the summer months
