OK so I am changing over to synthetic oil, and had a question do I need to run some engine flush in after I drain the oil so I can clean some extra of the conventional out?

 

No, just pour the synthetic in put in a good filter and let it run... next time you change your oil you'll be flushing out the synthetic and whatever residue from the regular oil was left

 

hey i have been wanting to ask this question. What about when switching over from synthetic to regular oil. Is there something special i gotta do? and is it ok to mix 2 differnt types of synethetic oils? for example mobile 1 and penzoil synthetic brand. I heard its not good to mix but its ok to switch from symthetic to regular oil.

I don't think there will be a problem with switching from synthetic to regular oil. But the prices and the extra protection that u got with synthetic goes down the drain when u do a regular oil change. Might as well, just had used regular oil all the time cuz you are throwing your money away if u are switching from synthetic to regular oil.

 

Why is it a waste of money to switch TO synthetic? The oil offers better lubrication and protection that last well over 10,000 miles in most cases.

 

Use Amsoil oil.
PM talkinghorse for prices

 

if it's 10k miles of protection, i would want to do this too. is 10k miles or 10 months protection?

 

Duh, that's what I said. Synthetic offers better protection then regular oil and it would be a waste of money if he switches from synthetic oil to regular oil.
