I drive a 85 delta 88. I was told it's better for me to use conventional oil rather than synthetic! Is it true?

 

I believe its true.

 

If it is high mileage I doubt there would be any benefit to synthetic. If it is low mileage I would use it for sure.

 

^^^This.

 

You are going to find that people are as wedded to this issue as the Ford vs Chevy guys out there. Personally, I have been using Pennzoil (regular not synthetic) for over 30 years, and I have never had a problem. I have heard (but not confirmed) that synthetic oil might be better for the moving parts of an engine, but not as good on the gaskets. No confirmation on that, just stuff that I have read over the years.


I just think that if you change your oil an filter regularly, there is no point of the added expense for synthetic.


**NOTE** Before every one of you pro synthetic people start jumping down my throat, when I talk about using regular oil, I am referring to normal cars with normal driving conditions. I know that high performance engines and racing practically demand synthetic oil. I'm talking about cruisers.

 

I cruise (;

 

According to what little I could find on the 'net written by accredited experts in this field it will do no harm to use synthetic oil in an old engine in a good state of tune. Whether there is any appreciable benefit depends on your driving habits and maintenance schedule.
If you change your oil at frequent intervals then I doubt you will gain anything. Modern synthetic oils are designed for modern engines, but there is no reason they should not work equally well in old fashioned V8s. It should stay in grade for longer than so called Dino Oil, but how well it might perform in an engine with a badly tuned carburettor and excessive blow-by from worn pistons and bores is another matter.

My complaints on synthetics has nothing to do with it's lubrication propertied but with it's ability to seep through older style cork gaskets and leave your engine a wet oily mess. Just a pain in the *** on a show car...... Tedd
