nate-and others. in the links to websites i found 2 seperate places that specifically mentioned that syth will tend to leak more. but there is a reason. synth is 'thinner' and can weasel its way into cracks easier despite wieght(hence its better 'slickness') and so is only coming out of old worn out seals/gaskets that were previsouly sludged closed. it doesnt creat leaks-it shows leaks that were plugged with sludge!
the most important factor especially for our older engines is the ZINC content. as the other links showed make sure you read the bottle. and in general diesel rated oil will be better. im NOT an expert at ALL but i do think synth is superior to regular. mark --- In old-chevy-truck@yahoogroups.com, "vwnate1" <[EMAIL PROTECTED]> wrote: > > > Again ; > > There are NO ' dumb ' questions ! . > > That report is total B.S. by the way , by old men who are afraid of > progress.... > > Any engine ~ flathead , L head , F head , heck even a T head will > LOVE synthetic oils . > > If the engine is all full of sludge (common) you MUST run it no more > than 50 miles and then _HOT_ change it as the synthetic oil is > incredibly detergent and it _will_ wash loose all the sludge and > filth inside your old engine . > > It'll also seep a bit more but these were never oil tight to begin > with . > > Diesel rated oils will obviate any cam scuffing issues due to lack > if zinc . ...few understand oil . > > -Nate Ole Chevy and GMC trucks rule!
