I would like to add though with synthetic oil it does not lose/add viscosity because of the cold/heat, you could run 10w-30 in all temps it will still flow smooth it is not supposed to thicken.

I know people hate on it but it's as good as any. I did a reaseal at 120 k and everything was clean, no sludge.

If you change it every 3-5k, any old conventional oil will do. Synthetic is a waste of money unless your engine requires it.

Summer has gotten up to 120F granted that is not normal, but we do see over 100F and winter we routinely do get -30 to -45F and have seen -60F I like not having to worry about the oil not flowing on cold starts.

Both of these points of view are valid, funnily enough.

The manual does not recommend synthetics or semi synthetics, it says use oil grade API classification SF, SG. It does not warn against synthetics either, and it is normally taken for granted you can use any oil that matches or exceeds the manufacturer's specification.

Standard mineral oil like Penzoil is perfectly adequate once you follow temperature recommendations for use and change it often. It will be way cheaper for a car that gets regular changes.

Just the same it might be cost effective to use synthetic in extreme conditions like 92 SVX experiences. The fully synthetic does not break down and lose lubricating ability under very high heat loads, such as will happen to the mineral oil. I prefer the synthetic myself, but I'm happy that either will work for the EG33.

If we were to scan an Owner's Manual to pdf and save it in the How To section, do you think people might benefit from that?
