Mister S hit a home run. Synthetic oil will NOT change any clearances any where in any engine. It may however tend to leak here and there because of the superior detergent package. It will immediately start to remove gum and varnish. It cleans so well varnished caked on gaskets don't have their usual crap build up to plug the usual gasket leeks.
Synthetic detergent packages do not remove either steel from crankshafts, cylinder walls, lifters, wrist pins, pistons or rings. No bearing loss will result from using synthetics.
Think about it a minute. If synthetics dissolved metal it would be worthless in any motor. General Motors would need to replace every ZO 6 Corvette Engine in the past two yrs. Because of dissolved metal clearances.
Has anyone heard of Mobil oil company replacing motors do the engine damage do to sudden clearance problems? Why does 2/3 of all Craftsman Truck, Busch and Nextel cars use Mobil 1? Not because the oil causes clearance problems I assure you.
If any one's intrested, go to Joe Gibbs Racing Oil. You'll be shocked at the type and viscosity oil used in all Gibbs Cars.

okay okay... you CAN run different weight synthetic oils... its not that the synthetic oils are thinner... or have smaller molecules... its just that they have a higher Viscosity, thats the point of laboratory work to make them... This means that the Problems with Thermal Breakdown that you deal with in petroleum based oil just isnt there... which means that they stay THICKER to a higher temp... and THAT will not lower your oil pressure, but rather raise it...
they are a smoother flowing oil though... not a thinner oil, that is why they will exploit leaky seals and gaskets... but if you have all that, then you probabl need to rebuild... the detergents change between manufacturers... and while mobile 1 has alot of detergents... both Royal Purple and AMSOIL dont use it, because there really isnt the need for it with the synthetics as they dont leave residue... but your best bet it to call the companies and let them explain it to you.
EITHER WAY it will not DAMAGE your car... its motor oil

It is not good to switch up to synthetic oil if the car has not been using synthetic since it has had low miles. Synthetic oil has smaller molecules than regular oil and can cause costly leaks such as rear main seal amd crank seal. These leaks are very expensive to repair. If the vehicle has high mileage I would recomend a good 10w-40 or 10w30 wieght oil. Good Luck!

You don't want to use synthetic oil in an engine that old. There's a lot of varnish built up, and the synthetic will cut the varnish loose. The varnish actually builds up and compensates for some of the natural wear on the mains and lifters, etc. When the varnish is dissolved away the enging will clatter, and make noise, the components are fitting looser. Plus, synthetic oil decreases oil pressure. Never a good idea to use synthetic in an older engine.

You won't encounter any difference at all from comventional oil. oil is oil, Synthetic just means its man made, and not refined or derived from crude oil. It does do a much better job than its conventional counterpart. It still needs changed at the same intervals. All vettes since around the late '80s to early '90s have mobil 1 as factory fill, and a warranty requirement.

no, it will be good for the engine, synthetic oil is the cadillac of oils, all new corvettes come with synthetic oil in them from the factory and is recommended for them.

It can't damage anything, but if you have any small oil leaks, they might get worse because synthetic flows a little easier.

hey buddy with an older car like that you dont want syn oil. go with a thicker oil unless its rebuilt because the bearing are worn so a thicker oil actually is better. syn oil seeps also

I've been running Mobil 1 in my 78 since 2001 when i bought it with 45k miles on it. I have not had any problems.

No; however, it was designed for plain old motor oil. Synthetc is a waste of money, unless the manufactuer recomends it.
