Is there anything to unclog oil? Options

[MeMoe]

I'm just wondering if there is any additive you can add that can clean the oil and unclog pipes.

I read in one of the threads that the celicas from 96 had a problem with oil clogging - any more info on that?

Thanks =)

you can run a quarter of dexron automatic transmission fluid through your engine right before an oil change.

This will break up any sludge.

However I strongly do not recommend using an engine flush on a gunked up engine. When you poor aggressive cleaning agents into your oil, you run the chance of dislodging a large piece of sludge that can clog a lifter/oil passage and the sludge can work its way into bearing tolerance and lastly completely clog an oil filter.

What I do recommend is to gradually clean your engine out with frequent engine oil changes. So far the best oil to use to clean your engine is Pennzoil Ultra.

also using synthetic oil and regular oil changes will keep your engine as clean as the day it was made.
