Just wondering ,I have 230000 klms on my sse is it wothwhile changing to synthetic oil,I am pretty sure it had regular oil for its lifetime.Thanks

I switched to synthetic @75,000 miles. So far so good. I've heard some people say they started having oil leaks after switching. Mine already leaked, so I wasn't too worried about that. I've heard it will keep the engine cleaner and stay stable longer. Keep in mind it costs twice as much as dinosaur oil.

I can't see any reason swtiching to syn would be bad as long as you stick to the same weight. If there is a oil leak now it will be there when you switch and possible get even worse. But give it a shot.

Does anyone really feel there'* and advantage to synthetic oil? I find that as long as you change the oil on a regular basis, that'* the best medicine.


I can only talk from my own experience.

Synthetic doesn't break down and therefore does a better job. With that said..I took a 91 Grand Am to over 200,000 miles on dino juice. It'* downfall was after I sold it the dummy never did an oil change..it ran for 2 years like that.

So there are no huge advantage to switch now.Ok Dino it is.Thanks

The biggest advantage is that it stays stable longer so you can leave it in longer. Newer cars are going a lot farther between service intervals and are more demanding of a higher quality lubricant.
I'm not sure where I discovered this, but the filter for a 4.3L Chevy V6 mounts to these 3800s and with it'* greater length provides more filtering area. I always ask for a 1990 model because I have a 1990 LE and it'* easy to remember. I can't say with absolute certainty that it will fit other trim models or later years but I use them on my C engine and it fits without any clearance problems. Bear in mind that you'll need to add an extra half quart or so when using the larger filter. My oil change takes 5 quarts. Before, with the small filter, I always had half a bottle left over.

Right, It'* Dino for me. Although you could do what The "bastard" and I do and that is use the PF52 "long" FIlter in place of the OE PF47 "short" filter.
