What Oil Are You Running?

I have searched on hear to see what everyone is running and couldn't find the thread so i figured i would ask. I have been getting some white sludge build up in my valve covers and when doing a search about that people kept refering to(your running the wrong oil). My question is what oil are you guys running? I have a 383 that's running around 450-475 hp. It's a high RPM motor with a 600 lift cam in it if that matters. I'm running Valvoline diesel 15-w40. The people i have talked to told me to run diesel oil because it still has the additives in it. As far as the milky build up, I don't get my motor hot enough most of the time to burn off the condensation. I drive it about 10-20 miles to the nearest cruise-in or car show and that's it. So i guess my question is two part. ..

Thanks.
Dave..

Re: What Oil Are You Running?

I think that you shouldn't have that kind of build up, that isn't a result of what kind of oil is used. I use 10/40, internal clearance set to factory specs.

Re: What Oil Are You Running?

I was just going by what was said on previous threads. People where saying that they weren't running an oil with detergent in them or they weren't getting the car hot enough. I was trying to see what people where running in there cars to see if maybe i was running the wrong oil....Back in the day this wouldn't even be a topic..

I run Mobile 1 20/50. Synthetic does not suck up the moisture like others.

Re: What Oil Are You Running?

Valvoline 10W30 is great.
Mobil 1 10W30 full synthetic is great, but expensive.
I run a flat tappet cam, have no frills for over 5k using synthetics, not a dang thing wrong.
I used straight 30w rotella diesel oil and hated it, so did my motor, which is strange since everyone says to use it or the cam fairy will come to your garage and make your cam go flat.

The only Mustang I'd ever own is a Fender.

Re: What Oil Are You Running?

Dave,
10 to 20 miles should be enough to heat the engine up and get rid of most of the condensation. What temperature thermostat are you running ? I would stick a 195 deg one in there for the type of driving you do.

As far as oil goes, diesel oils have also lost a lot of the additives. Since the diesels now have to use emmissions devices such as particulate filters, the oil had to get cleaned up just like the car oil.

I know its a little pricy, but I would use the Joe Gibbs Racing Hot Rod oil. It is a synthetic oil, but has all of the anti wear properties for flat tappet cams. It also is supposed to have a lot of corrosion inhibitors for cars like yours that are not driven a lot. I think it's available in 10w30 and 15w50, I would use the 10w30.

Just my opinion,

Re: What Oil Are You Running?

I'm running an electric water pump so i'm not running a thermostat. My motor is a full roller motor also.

I have 2 of them and no white stuff problems.

I use a pcv that I plug when I play hard but leave connected most of the time, even on my 14.3:1 sr that only makes 2 to 5" of vac. Crap will just mozy if you don't herd it and I want it gone.

The sr motor doesn't have a stat and I cycle the fan and water pump to get some heat every time it runs for at least awhile anyway. That oil needs to see some heat for H2O to flash.

I do not have leaky intake gaskets which on car engines I have seen is the usual cause of white puke on the vc's.

I run Valv 30 in the zz4.

The sr high comp engine will get at various times: regular Valv 40, Valv 20-50 racing, Rp 20-50 syn(but not racing), and going to try rp 10-40 when it goes back in the car the next time. I am not a believer in running thin oil to gain <5hp.

Re: What Oil Are You Running?

Your 100% synthetics will actually handle moisture better than any dino oil. They encapsule the vapors and release them at higher temps. Good syns have more than enough ZDDP and additives to handle your rollers as well. I use Amsoil 10w-40 and mostly short drives with the Mrs. and never have any problems. Id steer away from new diesel oils as Bill mentioned, their additive packages have also changed recently.

David,
Without a thermostat how can you get the engine up to temp quickly ? Do you cycle the water pump ? Running the engine without water circulating can casue some pretty bad hot spots in the heads and the top of the cylinders.

Why would running an electric water pump keep you from running a thermostat, which is really what you need to do in my opinion ?
