Oil Changed - 6 Quarts Drained

I just finished a long, but successful oil change over the weekend in my '88. You guys probably won't care as much as I did, but I thought I would share, the bozo before me who owned the boat had over 5.5 quarts of oil in it!

I just finshed reading a thread regarding the capcity being right around 4, and I managed to drain 5.75 right out of the bottom of the oil pan & filter - no pump. I wonder if that was the reason the boat wouldn't go over 36 ?

He had the filter on so tight I broke my filter wrench, and had to drive a 1/2 socket extension through the center to get any torque to twist it off. Sorry to whine, just venting a bit.

I seriously doubt the proper oil level is four qts. Five or six would be the proper amount. 5.5 is possible if the original engine call for a long oil filter and five qts and the owner put on a short filter.

Thanks for the resopnse. This board is a great resource, because typically there is someone on here who has had the same issue as you in the past, or at least knew of someone who has.

The thread below talks about how it is very difficult to get all of the oil out when draining or pumping, and people with years similar to mine only seem to be able to get around 4 quarts. The fact of the matter is, I got almost 6 quarts out, and who knows how much was still in the bottom of the pan. But I do agree, the first time you hear 4 quarts for a 351 Ford you think twice:

Are you sure it was all oil? I once had a mechanical fuel pump get a diaphram leak, which put gas into the oil.

Just something to look at/smell.

If you had a qt & a 1/2 over, it should have blown seals or spewed out the valve cover breather or PVC valve, at least registered high on the dipstick. It's been a while since I had a 351 so I don't recall how much oil they held, but it would have been causing problems.

Thanks for the feedback! Now this is really getting concerning! I didn't notice any gas in the oil, or in the pan after draining fortunately.

The drained oil sat in the pan for about 3 hours, and if there was fuel in there you would have thought it would have seperated out by then. Plus there was no fuel odor, just stagnent oil.

You have a good point, Airjunky. I'm not sure what's going on at this point. I just know the pan was reading 5.75 quarts, and most on here are stating that this era of marine 351W's have capacities of around 4 to 4.5 quarts -- maybe it was just a the verge of spewing/overflowing. Thanks again.

Haven't read the rest of the thread, but depending on filter (long vs. short), 5.5 isn't unusual. That's what I pulled out of mine last fall (dealer had done the last oil change). Zero mechanical issues last season.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

Page b-2 states 5.5 qts with filter change. Now that is for the newer chevy engine, but I can't believe the 351 would be any less. I used 6 qts in my 88 tristar with a long filter. Should be the same engine.
