Jesus, not again. Use synthetic oil. If people tell you it creates leaks, they are wrong. It may identify previously existing leaks with dino oil, but not create any...

And my LT-4 says 5w30 on the oil cap. Use Mobil 1 full synthetic, whatever viscosity your manual/engine suggests.

As you can see you hit a nerve with another oil question, lot's of opinions. I use 10w30 mobil 1 synthetic in my L98, but I am in warm climate. I would suggest using what your owners manual says. JMHO

I know you're new, but the point they are trying to make is to utilize the search function. You can locate many answers to questions you may have.

It's simple, flat tappet cams use dino oil. Roller cams use synthetic.

Unfortunately, even this isn't sure any more. Many of the additives flat-tappet cams require aren't even dino oil these days. Damn tree-huggers. (I'm joking of course. kind of)

Don't take it personally

If everyone used search there would be nothing to read. You can spend weeks researching which oil to use and find absolute proof of nothing. It seems to be opinion.

At 6K a year you could use old cooking oil and probably get a couple of years out of it

I am trying to say "welcome aboard" and use whatever oil YOU are comfortable with. They are all slippery

Default One word Road & Track

Road & track has an article from a couple of years ago. I'll let you find the article but, one of the interesting point is they dynoed the car with synthetic and regular oil and found that you get 4-5 Hp by going with synthetic over regular oil.

Just click the "Archive" box, and select the overall "C4" forum in the right hand pane. Then search for whatever you need, and you should get pretty good results.

It isn't wrong. It just comes up often, and is heavily debated.

I think it's important to remember that we were all 'newbies' once. If this is to remain the best forum going, then be kind to the new members. We could beat dead horses on a great many subjects and we have.
