Subject: Synthetic Oil
Content-Type: text/plain; charset=us-ascii
I recently rounded up a nice selection of new unopened NAPA parts that I
never installed on previous cars I owned and struck a deal with the local
NAPA to trade them for parts for my current vehicles.
The exchange went off OK but all the vehicles I own is running great so I
didn't actually need any parts.
I settled on several sets of spark plugs etc etc and two cases of 15/50
Mobil One synthetic oil.
My new engine has 5K on it and I'm satisfied that its not going to blow
up anytime soon.
I'm considering going to the synthetic oil but I like taking a look at my
oil more often that once or twice a year. Considering changes at 6k
rather than the normal 3k.
I understand that once you go to Synthetic oil there is no going back,
based on general opinion that the engine sets itself for the synthetic in
some subtle ways. Which I'm not fully advised about.
I'd like to separate the fact from the fiction:
#1. Synthetics run cooler ?
#2. They have less thermal breakdown that dyno oils?
#3. They handle the heat of Air Cooled better than dyno oils.?
#4. You can't go back to dyno oils after you've run your engine on
synthetics ?
#5. Oil change intervals are at 6K rather than 3K?
#6. Can I still run my quart of Marvel Mystery oil for 500 miles before
oil changes?
#7. Are synthetics more prone to leak than dyno oils?
#8. Are the current version of oil seals, O rings compatible with
synthetic oils?
#9. If the engine sets itself in some subtle way to require synthetics
after its been run on them ,,,,,,, what are these changes?
#10. In an emergency, (like blowing lots of oil) can I add a quart of
dyno oil to the pan without engine damage or ruining the lubrication
qualities of the existing synthetic oil.?
#11. If I went back to dyno oils after, say 30K, what could I expect?
If you've got anything to add that I haven't addressed here, I'd like to
hear it.
