Oil and Filter Question

[Gallep]

Not sure if this was mentioned. (to much to read )But IIRC, If you use Syn. oil, you can't use conventional oils ever again b/c of the saturation properties of the two oils have on gaskets.

I do not believe that that is true at all. And I have done it many times. For awhile there were rumors going around that synth caused leaks in gaskets.. some really old gasket material apparently did have issues but anything from early 80's on is fine.

Where are you getting this info from?

Not true. If it were, why do we have synthetic blends?

I was told this in my engines performance class. It may be something else, it was long time ago. but i'm curious now so i'll ask my old instructor and post a correction or the reason for this.

gallep--

if you're instructor seriously told you this bs give me his name so i can come do a gasket clinic for him. modern gaskets do not saturate with oil of anykind. if oil happens to permeate the sealing surface usually it is due to hard parts warping or flexing. this may cause the gasket to leak but the kind of oil that is in a unit has no bearing on the gasket at all.

trust me on this one.

(Trust me, I looked at it tonight.)

yeah, so i ask that instructor about this, and it was for a specific auto tranny, not an engine. sorry :P
