synthetic oil

[busbo]

I have a 1990 full size with a 351w. I changed the oil and filter this weekend and mistakenly added synthetic oil.

Will this have any negative effects on the engine? Do I need to drain and refill with new oil? Anyone run synthetic in their Bronco?

Thank you.

I only run synthetic, my buddy is an Amsoil distributor, so thats what i use.

**** no synthedic is what i run it is way better than regular oil ..... but alot more expensive , some people dont like running it in the winter cause it tend to get thick but since you got it in **** keep it is actually gonna help what was the weight ??

...you should make sure you have the same wieght if you mixed them.

The general rule of thumb is that synthetic oilwill last twice as long as conventional oil, so technically it costs the same because it is generally twice the price. :blink:

If your engine leaks at ALL do not use it! Itll find those leaks extremely fast and will leak faster...

I heard a rumor that if you switch to synthetic oil you can't switch back because it will damage your engine. I don't know if it is true or not but that is just what I have heard.

It was Motorcraft 5W-30.

Thanks for the quick replys. I feel a little better...I think.

The answer is True (from what I know) however, I am not sure what will happen if you do switch. If you use "Blended" oil you can go back and fourth without any problems.

I have a few leaks in my Beast so I use the blended rather than full synthetic.

Justbust1n It is correct about the leaks, think of it this way Synthetic is slipperier than regular oil.

Maybe you guys should read the information at this site and decide if you really want to use synthetic oil. http://www.lubedev.com/ and http://www.smartgas.net

Hey guys...............I use Castrol full synthetic in my wifes Malibu.........and on ocassion I throw a little in my truck if I dont have my stuff. Castrol says its compatible with all oils ( synthetic and regular ) Do I need to be concearned???????????? We did loose the oil pressure switch in her car about a month back..

I change my oil every 2000 mi. anyway so reg. castrol is just fine for me. Im in and out of the mud and on the beach alot, plus I tow my boat all over and alot of my friends who own other than "FORD" trucks out of places they shouldnt have went into. Thats one of the reasons for putting in a duel remote oil filter. Spending $14.00 every 4 months is a small price to pay.

All I use is synthetic in my truck, but that was after a complete overhaul of the engine. Synthetic has many benefits but if you start using it in a worn engine you may end up with more problems than benefits. Like Bluesman17 said, it does find leaks easily and leaks fast. I had heard before that it doesn't take any special procedures to start using synthetic, but once you go synthetic you can't go back. I couldn't figure out why so I called a Royal Purple rep to inquire about it. I was told that many synthetic oils have their own propreitary blend of additives in the oil, most of these additives will bond to the metal in your engine and if you decide to go back to using regular oil this bonded additive will start to wear irregularly. But like I said, I run synthetic in mine and have no problems at all, so I really believe it just depends on your engine.

well i guess i need to stop changin from synthetic to regular i only put synthetic in when i have the money i thought it was good for it , but if i do engine work i always put the cheap stuff in .... damn didnt think it was that big a deal .... oil is oil to me

Well, we started using synthetic in my wifes car when it was new and neither of my trucks leak oil, So I should be OK right??? I guess I was pretty uninformed on this one as well!!!

If you have used synthetic over a period of time and aren't seeing any leaking or losing any oil, then you should be good.
