....a friend of mine told me once you go synthetic you can't go back. Just wondering if this is true?

 

No, it is simply a myth.

Completely.

 

then why do people say you have to stay with syn. once you start using it? there has to be somekind of worthless reason right?

 

I think its better not to mix different oil but then again they also sell blended oils now.

Because they're uninformed and are simply repeating the same myth they've heard. It may have started in the early days of synthetic oils when many were incompatible with conventional oils, but almost all modern synthetic motor oils are fully compatible with conventional oils and there are no issues with switching back and forth among them.

I believe that synthetic oil is better than dino in most areas. I just switched the other day and my car will get nothing but synth from now on.

You know how when you change your oil you can't get EVERY drop of the old out. Well after getting completely done, i checked my dipstick and the fresh oil seemed to have a little old regular "swirled" in it. This confirms that they do not mix. I don't think anything bad is gonna happen and it'll be all good when i change my oil again in a month.

 

Older synthetics used to clot when you would mix with regular oil. don't ask y i think it has something to do with the chemical compounds that they leave in the engine. They have changed this in newer oil jus make sure when you buy it.

Yes, they do. You could fill the car with half conventional oil and half synthetic, and it would be perfectly fine. Even the label on your synthetic oil should state something to effect of, "Fully compatible with conventional motor oils".

 

the new synthetic oils are interchangable now, the "myth" started when synthetics first came out, and at that time they were not interchangable.

however motorcycle synthetic once you start using synthetic you cant go back.

I actuallly practice this myself. No problem in any of my cars.
The reason I don't buy "semi-synthetic" is because the synthetic content can be as little as 5% according to bobistheoilguy.com

I was using mobil 1 but I switched back to regular 2.50 a qt oil. Nothing wrong with my engine from switching back. $15 dollar oil changes FTW!

 

I got 5 qts of full synthetic for $13. Sure its supertech oil from walmart but for a synth break in it should work. I think i'm gonna switch to Mobil1 in 2 months.
