2 quick ones please.

how many quarts to completely dry fill in an 8v92 with the filter change?  24, 26, 30?

what happens if you put about a quart or a gallon too much?  ( besides oil leaks until it gets back down to normal)

Tom -

The vast majority of V-block two strokes in bus applications take approximately 7 gallons of oil when you change it out, including the filter.

Suggest you fill the new filter with oil before you install, as has been recommended here several times over the years.

So, fill the filter with oil, and add six gallons.  Fire it up and let it run for awhile (best on fast idle), then shut it down.

Wait til morning, then top off as necessary - maybe a gallon, maybe two quarts, whatever it takes, and you'll be good to go.

Oh, and make sure your dipstick is accurate - the "full" mark should be 1" below the oil pan/engine block interface.

FWIW & HTH. . .

thanks for the usual words of wisdom.

i got lazy and had it done while doing a lube.  i could have sworn williams did 26 quarts, but this time the garage did 30 and i thought maybe they mixed the capacities with a 60 or something.  i'm also about 1/3 inch above the full on the dipstick, but it looks like it is a handmade version so i really didn't know how accurate.  i usually only fill to 1/2" below the full, and don't leave so much on the pavement.  this one is leaking a bit more around the front of the engine than before, onto the pavement.

and of course i'm parked on clean concrete in a friend's driveway.  guess a little degreaser adn scrub will help that, along with elbow grease.

in any case,  what about the 2nd question.  what if i had over filled it?

Tom -

You sure Williams put straight 40wt in your 92?

As for your second question, as little over as it is, probably no harm done.  If it was one or two gallons over, then you could end up with the crankshaft creating froth, and that's not good, foamy oil doesn't lube very well.

thanks again guys.

rj, the guy at williams was as old as i am, and retired 3 mo later, after 30 yrs.
i'm sure he used the right stuff.  that's all i've put in also.  40wt rotella

this time, they filled it, ran it a bit, checked it, then topped it off.  i got charged for 30qts, so i'm sure that's what he put in.

obviously, the dip stick is just a a little off in reporting full before it really is, but probably just a quart.  i think i'll continue to run it just a little below the full mark.  Less leakage.

i could not easily find the capacities in the manual, honest.  i did look.

FWIW-I put 7 gals in the pan and filter and leave 1 gal in the resevoir. Works out real well with buying 2 gal containers. The level is always 1/4" above the dip stick when all has ran back to the pan after checking for leaks. I guess that means it takes 28qts dry. 1983 8V92TA Silver. My 2 cenavos, Will
