i've never used a synthetic oil before but plan i using it for my vette, other than draining the oil and changing the filter is there anything else that should be done, ie: getting the engine flushed or anything?
I didn't do anything and everything turned out fine. The only thing I know to watch for is if you have any oil leaks at all synthetic oil will make it leak even more. Synthetic oils will expose even the slightest leak. Other then that I don't know of anything else you have to do.
I thought I read somewhere that synthetic oils have some kind of detergent property that will break apart any crud and deposits you have in your engine. With that bieng said I would change it sooner then recommended for the first few oil changes. Dont want sediment moving around with your oil.
Your 89 pre-dates synthetic oil just a bit. One of the biggest problems is that early gaskets don't seal well against synthetic oil. If you were doing a re-build with new gaskets I'd say start it up on synthetic absolutely. But, an engine with original gaskets and some serious milage, I'd really think twice about the change. Try a synthetic blend like some of the extended milage oils like Mobil 5000 or one of the others if ya want to streach your changes out a bit.
I changed an 89 Riv with 100k over to sinthetic oil . Up till about 200k I only added about half quart per 3500 miles.Then the valve covers started to let go now it is up to a quart per 3500 miles. I would change the oil early the first time , maybe at 1500 or 2000 miles. I to believe it can clean grime from the engine. What sometimes does happen is the oil cleans the grime away from gaskets that are bad and develop leaks.

yeah, i think i'm gonna stick with the regular oil, right now she's running like a charm so no need to screw things up. thanks for the advice everybody.
Aircraft are required to use only synthetic fluids because it is significantly more reliable, more efficient and, most of all, less combustible.
Regular oil is made from petroleum and then manipulated with refining and additives to provide it's characteristics. It will eventually break down because it's base is organic. Synthetics are mineral and chemical based and remain durable much longer. Some oils are even considered eternal, given total filtering and replenshment of loss, but that's an impossibility in actual application.
Because synthetics are purpose built rather than modified from a base substance, they more closely match the intended viscosity and have a higher lubricity, significantly reducing friction. I put Mobil 1 synthetic in my engine and B&M Trick Shift synthetic in my '84 Coupe and immediatley saw a 5-mph increase in fuel economy. Ran better, too.
