dang your right! academy has the premium plus 19.99/gallon wth is up with walmart prices! ill be switching to quicksilver. just bought a case from academy..... if anyone cares, I work on vehicle engines a lot as a side business, lots of the cleaners screw up the sensors in our fancy motors, i used to be a seafoam advocate until i saw how it burned and the damage it caused, in order to clean the combustion process up most of these have lots of alcohol in them, while its a good solvent and does indeed clean it does not go so well for the sensors......YES I KNOW THE CAN SAYS SENSOR SAFE! but i have put it in a tank of fuel and watched temperatures soar on my laptop from seafoam trying to pinpoint why sensors were failing.... now i just run gas and oil nothing else......if yall want more info you can message me...... oh but i DO run 2 stroke oil in my duramax.......to lubricate injectors since obama is taking the sulphur out of our diesel fuel
Sea Foam has under 25 percent isopropyl alcohol in it according to their MSDS. A can at 16oz in a tank of 20 to 50 gallons means you are introducing something less than 4 oz of alcohol to either a tank. 128 ounces per gallon and that is less than .2 percent increase of alcohol in 20 gallons and under 1/10 of a percent increase in 50 gallons.
Most of the people who use these treatments have had zero sensor problems using it and I've heard many reports by of successful use of it over the years. In fact if you choose not to use it or any other treatment your carbon deposits in your engine will be noticeably worse. Sticking rings cause many engine failures and no treatment increases that risk. If a person chooses a different gas treatment like the Mercury Quickleen it uses a smaller dose per treatment and is just slightly more expensive than Sea Foam.
PS, ULSD came into use in 2004 and mandated in 2006 followed by all on the road diesels required to use ULSD starting in 2007. ULSD has a low lubricity index but its mandated to have lubricity additives put in it although there is nothing wrong with adding a little something to help it out.
Jay Smith, a noted high volume engine rebuilder and racing engine builder likes Pennzoil. He is retired but worked in the oil industry and did rebuilding as a side job for decades. He rebuilds several engines a week. He also says he hates Amsoil and any full synthetic in any steel sleeved engine although there seems to be many who use it with no problems.
I use Pennzoil Premium Plus but at that price Mercury Premium Plus is not too much more expensive. I've never read one test that indicated that Mercury oil does better so its really to me just run what you have confidence in. I don't use manufacturers recommended branded oil in any of my cars either.
I think Mercury Optimax oil is not TC-W3 certified. Their Opti oil is not TC-W3 oil certified as it does not meat their certifying requirement. Thats not to say its a bad oil. Its just not certified.
