synthetic oil

[06cumminspower]

does anyone run synthetic oil in thier stroker? will it yield positive mileage gains? and also i heard that the older the oil gets the worse the mileage is (due to the oil pressurized injectors) so would i have to continuosly change this synthetic like a conventional oil? any experience or suggestions is greatly appreiciated.

I have been running Mobil Delvac 1 synthetic for years. Engine is a little quieter with it. Don't know about mileage gains as I have ran it for years and years. I change mine every 5000 miles but some guys go for extended changes by adding bypass oil filtration systems.

good question. Iv been thinking of making the switch too, now that
i have 50k on the odometer.

iv'e been running rotella 5w40 synthetic for more than a year now. with conventional oil, i notice the mpg start to drop around 3,500 or 4k miles. with the synthetic it seems to start dropping around 8,500 or 9k miles. otherwise, milage has been about the same. now i only change the oil and filter once in 10k miles instead of about 3 times with conventional oil. save a few bucks that way, even though the oil is more expensive, i need to buy it less frequently

thanks, that was the kind of answer i was looking for. what kind of mileage drop do you see when the oil starts getting older?

I always ran dino in my 95 (chevron delo) and was consitantly getting 18 mpg with it. Never saw a drop in mpg towards the later end of an oil change cycle either.

i think it drops about 1 mpg or so. or at least the performance seems to be a little lower late in the oil change cycle
