Switcing from synthetic to standard?

[blueroo]

Ok, my six is still leaking oil. I know it's not the fuel pump, I keep checking that periodically and it's still leaking. I'm currently running Royal Purple full synthetic and I'm not sure if the consistency of the RP is causing it to leak or something else is loose on the engine. I want to switch back to standard oil to see if it still leaks.

However, my dad suggested I ask to see if you can go straight from synthetic to straight, or do I have to do it in steps, i.e. go to a partial synthetic blend, and then to standard. Any input is greatly appreciated as RP is too expensive of an oil to leak.

No worry, switching back and forth will do no harm whatsoever. If it has a leak, it will probably still leak but there is no point in leaking expensive oil.

ive heard plenty of people say to never change an engine from synthetic to standard, but thinking logically, theres nothing that would be damaged.
synthetics are known for finding places to leak, but i dont know why
go for it--josh

just fix the leak!

so you cant tell where its leaking from? any chance that it may be burning?

I had the same problem with one of my cars. Synthetic would "dissapear" though standard oil would stay full for until the next change. I couldn't figure out why so I just stayed with standard now. I couln't notice much difference between the two anyway except on the really cold winter days.

It's not burning off because I see the evidence of the leak on the garage floor and on the side of the block.

clean it off really well, let dry really well, then go for a short drive.

You can use baby powder for a "leak detector"

If I remember right, he knows exactly where the leak is (fuel pump to block?). It is just that no matter what he tries, it still leaks...

Shouldn't be an issue.

The more experience I get around cars, the more I realize that most of the old "Don't Do's" are really just guesses. It's not as if mechanics have done controled tests of "if you switch from one type of oil to another then your engine will explode" experiments. Oil is oil. Synthetic is good for some things, dino for others.

Heck, according to most mechanics, my truck shouldn't be running. It hasn't held oil pressure (verified with a mechanical gauge) at idle in 5 years (60k miles) and still runs and sounds as good as the day it was new (210k miles on it).

My 170 Maverick did that. The oil light didn't flicker, it was SOLID on when idling. ran like a champ!

Yeah...but for some reason I can't renew online and I keep forgetting to call them when I get home. I'll try to get it up today.
