I too would recommend a synthetic oil over Slick 50. Slick 50 will void some warranties, for what it's worth.<p>----------<br>Mike Reynolds,<br>GrassRoots Lawn Care, Florida<br><p><font size="1">Edited by: GrassRoots Lawn Care
I was having trouble with my cars standard transmision. Hard to shift and grinding gears. Changed the oil, no change. Changed the oil again to Slick 50. It is like new.<br>That's all I know<p>Once is never<br>Twice is always
Slick 50, amsoil, mobil1, prolong, they will all make a difference in thge summertime exspecially but the go forever without changing your oil is a myth you need to change your oil just like regaular oil changes and that is what will make your engine last the longest.
I wouldn't compare Slick 50 and Prolong to synthetic oils. They are not the same and i would avoid the use of PTFE products.<p>Articles worth reading:<p><a href="http://vtr.sanders.com/maintain/oil-additives.html">Snake Oil</a><p><a href="http://www.mustangworks.com/technical/articles/misc/OilNotes.html"> Ed Hackett's Oil Notes</a><p><p><p><font size="1">Edited by: Keith
One thing i dont agree with. In the article it says that sythetics can go three times linger than sregular oils and i just look at my dipstick and when it turns black and has metal deposits and feels scratchy when you rub your fingers together and you can feel a difference in your engine then its time for an oil change. I do beleive your article about additives and will say that synthetic oil is in my opinion better that any additive because it takes up your whole cranckcase instead of just alittle amount of concentrate just poured in to make a big difference.
bdemir, a synthetic will resist heat related breakdown longer than petroleum if it was in a perfect enviroment. You are right, 3-4 times as long is a bit much to be expected. In an internal combustion engine, oil becomes contaminated quickly and this is the primary reason for frequent oil changes. <p>I change mine (Kohler) every 100 hours w/ filter. Using a high grade filter is just as important.
I change my oil every 50 hours and the filter every 100, which is 1/2 of what is recomended. I figure it is cheaper to change the oil than it is the engine.<p>----------<br><a href="http://pages.prodigy.net/eric.erickson/">Eric@ELM</a><br>The Grass is always Greener on the other side of my competitors fence
