need oil change pre 92? read this first!

i was bored so i changed my oil today, canadian tire didnt have the filter i needed so i dreaded going to the dealer, amazingly it was 17 bucks!, CT charges me 27.50!!!

thats one the side.. when i went to the dealer i asked for the synthetic oil and he asked why,

the service manager told me that all cars 92 and previous should NOT run synthetic oils, it will cause premature breakdown of the seals!!!

he strongly suggested i use standard oil and he even showed me the oil he uses in the service dept, belive it or not he uses castrol 5w30, yup basic canadian tire $250 a litre oil
if your car is 92 and previous dont waste your money with $8 per Litre on synthetic oils cause it drains the wallet and is bad for the engine!

I don't know if I buy this. Why why would synthetic be bad for seals? Certainly it can clean your engine, and it will make you burn oil if it was very dirty, but actually causing damage? I dunno .... Mines not <92, so it does not affect me, but it's still an interresting post. I'd like more info (and maybe proof)!

Synthetic oil acts as a detergent cleaning out all the gunk out of the engine including all the gunk that accumulates around the 10 year old seals preventing them from leaking. This is the reason why dealers do not recommend switching old cars to synthetic oil, since the new thinner oil may start all sorts of oil leaks.

Do you think that this could be a possible explanation as too why when I changed my spark plugs last week, I found oil on them? Not on the outside (leaky valve cover), but on the end itself. I just switched to synthetic for a period of roughly 2 months before I put the car away.

usually the oil would be looking like sludge and be black and thick from all the heat, or was it just like oil from the bottle?

It was tres bizarre. All of the plugs were black with carbon deposits, but cylinders 3,4,5 had oil like just out of the bottle on them. Now i haven't been driving the car, but how would oil make it past the rings in that clear a form?

Well yeah it was. I thought that it was on end of the spark plug, but it may have just gotten on it as I pulled it out. That is a sign of a leaky valve cover gasket though, and I had mine replaced last year, so I wouldn't think that would be doing it. What other problems could cause it do you think?

Well that is what you would think, but I know that when the valve cover gasket leaks you do get oil in those shafts.

There is a link.
