Michael, many of the other car clubs have on going discussions on oil. From
the literature, test of oil in various situations, and personal experience of
mechanics and owners, and myself, this is what I have gleamed.
1. Synthetic oil has superior cold flow, and hot temp protection over dino
oil.
2. In cars that are not used often, or are driven for short distances,
synthetics are superior, for many reasons, but a main one is that you do not
get the varnish and sludge as with dino oil.
3. There is a myth that older cars or engines that start to use synthetic oil
will leak, because the gaskets are not compatible with synthetic. This is not
true of the synthetics of the last 20 plus years.
4. The cost of synthetic is more expensive than dino oil, but if some of the
situations above fit you, then the extra cost is minimal, and worth the
expense, especially #2.
5. Various test done by hot rod mags, have shown increase in hp and torque with
synthetic oils.
In another use, synthetic lubricants in trans and differentials offer better
cold flow charastistics, as well a lubricating functions.
