Oil Pressure

I got 6 quarts of 30 wt will try this and a can of stp do i add all this to the oil or go like 5 quarts and the stp? thanks

I wouldn't use the STP. I'd go with SeaFoam. It'll clean out the oil galleys slicker'n slugs through a goose.

Remember, when you do something like this... be prepared for unintended consequences. The darn thing may just pop a leak here or there, find a weakened freeze plug. So, if that happens, don't be dismayed... just deal with it.

His initial problem was low oil pressure, which Sea Foam won't help and might exacerbate. Only use for here Sea Foam is if the pickup screen is partially clogged with gunk. I wouldn't expect that to be a problem unless the engine has been thoroughly sludged.

I'd stick with the STP.

Do i go 5 quarts and the stp or do full 6 quarts plus stp?

Follow the instructions on the can.

The 15 fl. oz. STP® Oil Treatment products are designed to be mixed with 4-5 quarts of motor oil.

Put in five and the STP, get pressure up, shut it off and check the dipstick. Add the sixth if you need it.

Skip the STP. Use heavier weight oil like a 15w-40 and buy Auto-Rx if you want to do any cleaning. STP is not so good stuff. Get a 50 grade if need be.

Wait!!!!

Wait!!!!

Did you put an old school oil pressure gauge on it and see what it reads???

That really should be a starting point.

STP ???

Marco Andretti likely thinks that STP is a Socially Transmitted Disease. But ask his Grand Dad about it (or maybe Andy Granatelli).

But then the turbine Indy car and Parnelli Jones.

Man that brings back some memories....

But STP if someone still sells it - NO.

Oil has been improved over and over since 1985 so just use oil.

Using STP:
You aren't trying to clean anything.
You aren't trying to thicken the oil.
But you ARE trying to find out WHY it clatters.

STP will help with the lubrication. It's thick coming out of the can, but once mixed it isn't thick any longer.

Use 30 or 40 wt with the STP. Even if you are the few ounces overfull from the small can of STP you are still safe.

Multi vis oils have the additive that makes them multi-viscosity - it radically cuts down the lubrication quality. Notice high horsepower performance engines that really need good lubrication NEVER use a multi vis oil. Notice how thin 15-40 wt is on your fingers. Now try 40wt to compare. Then try STP on your fingers - you can see THERE IS A DIFFERENCE!

You are trying to FIND OUT whether you need to do mechanical work or not. This will help you find out! For cheap too! Much cheaper and easier than experimenting with a new oil pump, bearings etc.

If it still clatters and has the same troubles, THEN worry about further repairs.

Some don't believe in doing things the simple way - especially when it's not theirs.
