i went on the web site of microlon an it say this stuff last a life time no need to keep adding only once an your engine is protected for life is this stuff for real an it cost 99.99 for a 32 once can witch treat an 4,6,8 cylinder engine
don't waste your money.save it for oil changes radiator flush and tune ups when needed
companies like Mobil ,chevron etc spend millions of dollars a year doing research on additives to make our engines last longer, dont you think if theres something better they would add it to the oil? there have beenperformance additives since theres been cars , I am not going to disparage Lucas but most additives are just snake oil if you want to take care of your engine go out and buy full synthetic oil on your next oil change , this will save on engine wear, and fuel
Most people don't seem to know that modern engine oil has many oil additives already: (1) friction modifier (2) viscosity stabilizer (3) anti - foam (4) etc. And if you are not careful, the factory additive will negatively react with your after market additive. Some of these additive were important long time ago, but now modern oils is are complex cocktail of petroleum products. In general it is more important to get frequent and timely oil change than to use these additives. There are 4 most important maintenance items in your engine (1) engine oil (3k - 5K miles) (2) tranny oil (30K miles) (3) coolant (3 years) (4) timing belt (60K miles) Just keep those maintenance and your engine and tranny will be problem free. I have a 94 Civic with 187K miles and the engine + tranny + suspension runs like new. I get 41 MPG (doing 72 MPH). I can get even better MPG doing 55. Good maintenance pays off. good Luck.
