oil-5qts. 5w30 TropArtic,16 oz. SLOB,8oz. Marvel Mys. Oil, 8oz.Seafoam
OCI-Oil has about 140 miles on it and changed last November.
MY Ques IS-There are soft black balls or blobs of carbon on the dipstick that don't seem to be getting filtered out by my NAPA Gold/WIX oil filter. Did the Seafoam cause these blobs?
 
Hard to say what the cause is but one thing I can
say for sure is you have way too many different
fluids in that crankcase at one time. One special purpose fluid at a time, if at all.

I'm assuming the Marvel and Seafoam are in the fuel tank. Is that correct?

Agree with the other post. Here's what I would do if it were my slant-six.

Drain crankcase. If you like TropArtic, use either 10w30 or 10W-40. No additives added to either. After your tank of gas is almost empty either put in a bottle of Gumout REGANE or Chevron Techron. Just one bottle and don't put anything else in there for at least 3,000 miles.

I will say this, if you have TropArtic, SLOB, Marvel, and Seafoam all in the crankcase, well you have 4 different chemistries working to do different things and that's probably what's causing the globs you see. Might be the filter is full of this stuff and has kicked into bypass.

Nice truck.

Yeah, I'd pick MMO or Seafoam but not both at the same time. The SLOB is really no big deal but that's quite a cocktail. Of course, with the quantity of Seafoam and MMO you have in there you better pray you have enough anti-wear additives and that you don't compromise your lube's protection.
 
In addition to the multiple chemistries as stated before, I don't think the winter temps in MN has helped them mix thoroughly. They are probably seperating overnight when the temps drops. Though the oil may appear warmed up when the engine is running, it will not totally get up to operating temp since the oil pan is exposed to the elements and cool off oil from the cold metal pan. There's too much stuff going on with that strange brew to figure this one out.

What's the average and overnight temps there?

You should have those globs of carbon analyzed. Organic molecules, high energy environment... I believe you may be have replicated the origins of life itself.

Watch for attempts at intelligent communication from your crankcase.

And when the experiment is over change the oil to something that isn't a chemical oxymoron.
 
OK, I get the drift. No more "crankcase cocktails" I got the truck a little over a year ago and he never changed oil,just added.So,I thought I would try fresh oil with a new filter and additives,to get some of the "glop" out. I'm not going to use synthetics or auto-Rx because with a vehicle 29 years old,I don't want any leaks. Besides,I only drive it in the summer,so synthetic oil is not a good value for this app.Thanks for all the replies.
 
Yep,but never again! Went to Wally this afternoon and bought 2 gal. jugs of DELVAC 15-40.Oil pan holds 6qts. If I want a blend, could I use a couple qts. of 5w30 with the gal. of 15w40? Yes,NO,Maybe?
 
I'm sure it'll clear right up as the oil does its job on whatever those globules are. Mix oils? No problem IMO.

I think it must have had something to do with two different solvent products mixed in with the oil. Just conjecture... but oils of different types usually mix fine, and either solvent is advertised to mix with oils, so that seems the most likely cause.

The slant six is nearly bullet proof -yes? Use the reccomended weight oil for the engine. Do an auto-rx clean and rinse, then
stick with the reccomended weight oil for that engine afterwards.
I would reccomend sticking with one of the high mileage oils such as Valvoline maxlife.If you want to put something in the fuel to clean injectors or a carb then the chevron techron is
the best but not cheap. good luck
