hey fellas,
what kind of oil do you put in your classic car?
i was thinking of using penzoil....

 

Think more about Rotella... The oil they sell nowdays doesnt have enough zinc in it, so the flat tappet cams will go flat after a few miles. A roller will survive but a flat solid or hydrualic wont. Its made worse by having high spring pressures from performance cams, so if yours is stock, it will live a bit longer.

Not blowin smoke up your skirt over it.. Even HOTROD magazine had an article on it. Its well known in the Pontiac world, since they use alot of spring pressure and have big heavy valves...

Wouldnt you like to have 400ci and a 2.11 intake valve on a 14 degree inclination angle?

 

Thanks for that tidbit of information Todd. I hadn't heard of Rotella until you mentioned it. So, I did a little bit if research and found this. I am impressed. So, the next time I change oil in Ol' Yeller, I will have to go to a Shell station to get the oil.

How many miles are on the car?

 

Soaring you are better off with Mobil 1. Shell Rotella is a hydrocracked oil. It is not a true synthetic, so there fore you will just have less parraffin wax in the oil. It will act otherwise like any other dino oil.

 

I've used Vavoline products for as long as I can remember. We've had original motors ( save the typical timing chain and exterior parts ) go well over the 250k mark.

More important than the type of oil is the intervals you change it and the filter that keeps it clean.

IMO, of course.

 

I use catrols syntec 5w50 in just about everything. THis oil is awesome, in my stang I notived it would rev faster than with any other oil, including mobil 1, penzoil synthetic, valvoline synthetic, Quaker state synthetic. In lower milage engines, when I used this oil, after 5k miles the oil on the dip stick would look like I just poured it outta the bottle.
I run cars hard, and I mean REALLY hard, and so far this is the only oil IVe found thatll stand up to the abuse.
-P.

 

my car has 88,000 miles on it. but i dont know how many times it has rolled over if any...

 

Then you need to stick with dino oil. I still run dino oil in my 65, but use synthetic in my 03 Mach1. The reason I still use dino oil in my 65 is because the gaskets and seals are all original, and if I changed to a synthetic, the gaskets and seals would leak and I would get oil all over the undercarriage for awhile until those old gaskets and seals soaked up enough to quit leaking. Now, whenever you get an overhaul and get all new gaskets and seals, then is the time to switch to synthetic oil.
Yes, I am aware that the Rotella oil is a dino oil. That is why I responded with a thumbs up for that particular dino oil. However, Pennzoil dino oil is not the bad guy that a lot of folks seem to think it is. That is all that Ol' Yeller has ever had, and she has well over 130K miles and doesn't burn any oil and no funny noises. The trick is to change it often whenever you run Pennzoil dino.

 

I'd use AMS Oil full synthetic or even castrol...no pennzoil or royal purple...not as good of luck.
