No - in fact, your engine might just appreciate it!
No, you can even mix synthetic with conventional oil. It will do no harm at all.
If you have kept regular oil changes, no prep is required. Just go and put the synthetic oil in.
No it is fine to switch back to regular oil.
No. It will ruin an engine. The above answer is 100% wrong. You can mix convention oil with synthetic and it will do no harm at all. When you see them selling Synthetic blend that is what you are buying. A blend of synthetic and conventional oil.
No, as long as it is the proper weight. In fact I highly recommend synthetic oil be used in any air cooled engine.
can anybody say where the engine oil pressure switch in a car and can there be any engine oil leak through the engine oil pressure switch? The location varies by engine and yes, they can leak oil.
In a Brand new engine it is recommended that you get the rings seated before you start using Synthetic oils. So run your engine for 3,000 miles and then you can switch to a Synthetic.
Yes, this will cause no harm until the next service.BUTSome cars (Porsche for example) must use a specific specified oil or the warranty will be instantly void.
I'm not a mechanic / technician but as long as your engine doesn't burn oil or leak oil I would say ( yes ) I switched my 1995 Ford Explorer to 100 % synthetic engine oil back in 2001 and have been using synthetic ever since with no problems
yes you can synthetic oil can go in any engine
Yes, you can not only switch you can mix synthetic with conventional oil.
I have a 79 vette 350 and i use 10w40. you might want to switch to synthetic, i hear it is better for older cars. but once you switch to synthetic, you can't go back
