are fuel and oil additives a waste of money? i use fuel additive with increase lubricity and adds cetane. i use oil additives which prevent dry starts and decrease friction and reduce cylinder wash. while driving and listening to the road dog trucking show i heard a guest say that if oils and fuels needed the additives they would already be present in them from the beginning. they are an unnecessary waste of money. when i use these additives i can hear the difference in my motor especially when pulling a hill. normally when i pull a hill without any additives i can hear the pistons hammering away and if i work the engine too hard the hammering sound becomes a loud chatter. not with the additives; even on big hills the engine sounds smooth and quiet and the temp stays below 200F and the fan rarely kicks on while i pull a hill with these additives.without the additives, the engine runs hotter and kicks the fan in more times. how can he say that additives are a waste of money?
just a sledge hammer should should work.
You be the judge. If what you just said is true, they seem to work for your problem. I had a problem with my 1989 Trans Am cutting out under a heavy load just as if it wasn't getting enough fuel. The fuel pump and the fuel filter were changed not to long ago. So I figured -what h***. I dumped in 4 bottles of STP gas treatment and after about 3-4hours of driving the problem went away.you tell me if they work. I think it depends on who you ask. I know they do.
i don't know what kind of additives you are using but i can tell you FROM EXPERIENCE that Lucas engine oil products for the big diesel motors are crap. you should see the cam and rockers and how sludged up they are after using there products . if you can hear the pistons hammering than you may have a problem. what kind of engine are you talking about ? syn. oil is the best if you can afford it. most engine oils have enough additives if you use a good brand of oil. don't waste your money on the additives .
