is it ok to use regular oil???
 

As some of you may know... my car sprung a oil leak really bad behind the block somewhere... I think its either the sandwich, lines leading to the sandwich, or the o ring. I want to put oil in it and start it up and find where its coming from. Problem is that i use full synthetic oil. Its 25$ for 5 quarts of it and don't want to waste 25$ to find out where its coming from. Can i just use regular oil to find the leak??? or will it mess up something??? Ive been told never to mix them

Why not just drain the synthetic, get some cheap dino oil and use that to find the leak?

So is there some Full Synthetic in the car now, or is it drained? I wouldnt mix the two if one is already in there, but i cant see it being a huge problem if you drained out whats in there used the Regular, then drained that for all new full synthetic....

Not a huge oil guru, but i mean cars can switch from regular to synthetic so as long as its drained out i dont see it being a problem....

yea... im just not sure ya know.... Ive just been told not to go back to regular once its been full synthetic

Thats BS in my opinion. The amount of oil left after its drained is so minimal that it won't cause any damage. I've seen many cases where people switch back without problems. Plus, you're going to use it just to source an oil leak.

theres probably not much oil left in there. just buy 5w30 from walmart... its like 1.60 per QT.. fill it up with 4 quarts and lets start it up.

Do you have full synthetic or tri-synthetic?? Brand?? I asked b/c alot of people seem to have these confused.

You're not going to hurt the engine by turning it on with two different kinds of oil in it. Just don't go out and race it around with it like that.

I always run mobile 1 full synthetic.

Congratulations, you've fallen victim to marketing.

Mobile 1 is tri.

ummmm ok.


Spend One - What is Tri-Synthetic?

Its a honda, you could put Kerosene in the crank case and it would run fine. Use conventional it will be fine, it would just break down to high heat where synthetic wont. Other then that the are speced to the same lubrication properties. There is no reason why you cant switch.

Well i used mobile 1 cause i used to run the car hard. So I figured it would be better.

You won't have any problems mixing them.

But I think your problem is there is a sandwich in your engine bay. Food products aren't meant to run a car.

Hahaha...

It says on the back of the bottle of Mobil 1 that it can be mixed with any other oil.

^^You shouldn't mix synthetic with dino.

why not?





i dont see a problem running regular oil with the synth especially if its only to find a leak.

like previously mentioned, i wouldnt go around running it hard with both oils mixed in there... use reg oil, find the leak, then change it all out for 1 kind of oil

You can mix the tri-synthetic. It is fine. Just do it.
