What engine oil to put in my SBF

[Caprimaniac]

Hi.

I See, Bob- about the rear plumbing.

Although; I have a plug there (AN8, I think) and will make the house- routing "better". Yes; I have a spare 1/4" plug in the front, but consider it a little bit too small.

I do not have the check valve, but would consider plumbing the accusump with my oil cooler adapter (sandwich) if I had one lying around.

I wonder, Tom: are you oe of the famous Wells- brothers? In that case, I know you from the Capri-list....

Dyno Cat Proton RSX 10W-60 racing synthetic.

I maybe should have gone with the 15W- 50 RSX; but time will show how the 10W-60 works. Will be out on the road tonight. (I fired it up saturday; engine started right up after a couple of months where alot of the wiring had been altered and the some major alterations had been doen to the car.)

OK; DynoCat is a european brand, at least marketed in Norway (cannot find any other references; just a Chevyguy who, like me, is "lost" in a US- based forum where noone has ever heard of DynoCat... .) I think it is of Quaker State origin... and it might be identical to their 10-60 Ultimate Durability engine oil.

Well. That's very differant. Never mind.

But, burning a qt every 1,000-1,500 miles is a lot of oil.

I agree, you may have blow by from a ring or valve seal that's cracked.
Perform a compression/leak down check. With only 6,000 miles, that's not a good sign. Sorry for this thought but, check it soon before anything worse happens.

Mobil has a worldwide presence, & you should be able to find Mobil 1 synthetic oils. I use Mobil 1 15w-50, and have for over 9 years & over 37,000 miles in the same engine. There has been no measurable wear over that time & mileage span. No leaks either.

Engine not raced, but sees hard use from extended high rpm and supercharger.

A quick update.

So far I am very happy with the full synth 10-60 motorsport (aka quaker state 10-60?).

Increase in oilpressure while idleing warm engine. No 0 pressure at quick 360- turns (althoug not fully tested yet). Very little blow- out of crankcase evacuation hoses.

OK; idle is a little higher at 11-1200 rpm and maybe also more stable with 2 idle stop screws on the webers. Evacuation hoses have gone from 12 to 16mm (1/2" to 5/8") inner diameter (and vent tube from 6? to 12mm?). These things are also partly causing the positive results above.
