Well i just heard something that confused the crap out of me. For some time now Ive heard and read that synthetic motor oil is the best. I just got word that for some reason synthetic motor oil isnt good in a engine with less than 2,000 miles on it. Also heard that it isnt good for an engine with more thank 50,000 miles on it. The reason being is that it blows the seals in the motor. Is this true? My car has got 103K on it and using Mobil-1 Fully Synthetic. Let me know what you think...

there has been a big discussion about motor oils the plus side and the bad side on here. Please use the search button.

I have never heard of this happening neither...

oil shmoil, just run water in you're engine, much more cost effectice.

Chrsit on a crutch!! How many Oil v oil threads do I have to look at.

Why is this specific to 92-00 civics?

SEARCH!!!

Look on edmunds, car and driver, google, wikipedia, dogpile!!!!

I for one choose to believe all that is just a bunch of hype, run what you want. It all depends on how often you want to change your oil.

Motor oil is motor oil!!! If it "blew seals" in engines they wouldn't sell it!!

The only thing I've ever heard is to leave conventional in until the rings are properly seated. Then you can use synthetic. From personal experience, I've done just that with my new Accord, and it runs flawlessly.

I've also seen one case where this guy that came into my work. He had AMZOIL in the crankcase and he told me that he hadn't changed the oil in near a year. When I drained it, it looked like I had just put it in. It has some kind of crazy acid suppression in it, allowing it to keep its viscosity and protective ability for such a long time. Not totally convinced- I'm still a little sketched out about only changing the filter and not the oil for a year...

It isnt specific to the 92-00 but every forum has one. I wanted opinions from people who drive the same car I drive.

oil is oil is oil is oil.

After engine break in it doesnt matter as long as you use a decent filter and keep your oil change intervals at what they should be depending on the grade of oil

The concern with using synthetic oil during break-in primarily lies with the rings seating properly. Certain company sites (such as Mobil 1) will state that there are no issues with using synthetic on a brand new engine. Other sites (including Royal Purple, Red Line, etc.) suggest breaking the engine in using conventional motor oil. My suggestion would be to use a conventional oil for the break-in period, and then switching to a synthetic if that's what you want to run.

As for higher-mileage engines, synthetic oil will certainly not "blow the seals". The issue is that synthetic oils have the potential to expose leaks in degrading seals, due mainly to their increased detergent properties. If your engine is performing fine and currently has no leaks using Mobil 1, there shouldn't be any problem with you continuing to use that oil.

Amen.

so if i went from conventional oil... to royal purple.. and now i seem to be runn'n lower on oil... my ring seals ate away and now im burning oil slowly?

It's possible that the Royal Purple is simply being consumed more readily than the conventional oil you were using. Similarly, a number of ITR owners seem to notice increased oil consumption with Mobil 1. I'd try switching to a quality conventional oil of the proper grade and then reassessing the situation.
