Can't find my owners manual and can't remember if the beast takes 5 quarts or 6....

Anyone got a book handy?

Tim, this isn't the answer, but do you remember which era it was that didn't have the right sized dipstick. For some reason, that crossed my mind this morning, and I wanted to be sure to order a new one if I needed it before changing my oil this year.

I thought that was the transmission oil dipstick.

You may be right. Do you remember what years/engine? Sorry to jack your thread, Tim.

My Owner's Manual is for 1996 Prostar 190 and 205 it says
LT1 Oil Capacity................4-5 Quarts with filter change Verify with dipstick
Oil Type...........SAF 20-50 Racing oil
I guess that means that if you don't change the filter its 4 quarts 5 if you do.

Yeah i'm interested in which boat had the wrong dip stick, i think i'm having a problem with my tranny (it seems too full) and i think it might be that. Thanks. :D

John B,

Thanks for the help! I thought 5 sounded right but was starting to second guess myself.

Doug- before you order a new dipstick, why not call MC or a MC dealer and verify the part number? The short stick was an issue in '97 and/or, early '98. It was a GM problem and they didn't supply the right sticks based on mounting angle.

My 94 350 TBI engine came with the wrong dipstick.. I believe I got the correct dipstick # off this site a few years ago.. It was a 6 qt dipstick and sure screwed with me for a while until I got the correct one.... SO some of the engines out there are 6 qt capacity, not mine...... If someone can use it let me know........

Thanks, I just couldn't remember and didn't want to screw anything up. Again, sorry to get off topic (although I've seen it happen before).

More FYI:

'94 LT-1. 5 qts w/filter, perfect on dipstick.

Indmar told me Penz. Marine 15W40. Debating switching to non-marine 15W40, since the truck uses that too. Although I buy gallons for the truck & qts for the boat...

Anyone know the difference between Marine oil and auto oil???

08-10-2004, 02:43 PM
Remember the discussion on the old site? The marine is for extended high RPM running and has(according to Mercruiser), longer polymer strands to resist shear and viscosity breakdown. There's always google, too.

Pennzoil Marine is available in gallons, too. If they don't stock it, call around or find a distributor of Pennzoil to find a dealer who stocks it. I don't know if Moore Oil is just in Milwaukee, but if they're a national company, they do carry it.

I had a smarta$$ answer for you Rick, but I don't know you that well so I held back...

The old site is like me, kinda old. And remember the Mind goes second.. Do you recommend the marine oil Jim?? I do not use Pennzoil and really don't want to.......


Sure you do, and I am pretty thick skinned anyway.....

Anymore swimsuit pics you "Guhrly Men"?????

You're not that much older than me, but ......oh...uhh....what were we talking about? I used it, Indmar recommends it(basically through a marketing deal, but if it was blowing up their motors, it would cost them too much to continue).

For what it's worth, this thread reminded me that my '95 Prostar 190 (275hp) came from the factory with a short dopstice. The dealer replaced it with the correct one.

It always seems like my 95 takes 4.5 quarts with a filter change.

I prefer the synthetics especially Mobil 1. Syn vs dino is a very heated topic within the industry and I do not want to have a pissing match here but syn is far superior in all categories. Yes dino will work and is recomneded by the mfg but syn just adds that extra level of insurance.

If you are really interested google the topic and you will find all the information you need from independent testing in the industy. Or you can just take my word for it :D
