Guys,

I am trying to find out how much more (or less) oil a 2 stroke uses
compared to a 4 stroke.

Thus, I need to know about your 4 stroke motor (inboard or outboard):

- Horsepower, brand
- amount of oil it takes for an oil change (incl filter)
- how often do you change your oil (how many hours)
- how often does the manufacturer recommend you change the oil?
- Does your motor burn or lose oil? Do you have to top up in between
oil changes?

Thanks for your help!

Matt

I have a 4 stroke merc 60, uses no oil between changes @ 100 hrs.
Be sure to tilt motor all the way up and then back down before you check it or
change it so you drain out all the nooks and crannies.

Don't have specs in front of me, so I can only answer the last question
regarding my Johnson 1996 15 hp 4 stroke (model J15FREDR). It consumes NO
oil between April and November. Zero. I change it twice during that time
period, and based on memory, that's about twice as often as OMC recommends.

210hp, Mercruiser 5.7L
5qts
At end of every season (about 60 hrs)
Not sure, think it's every 100 hours
Have never added oil between changes. Checked every trip.

You're welcome!

Ok How much oil do you need for an oil change?

Thanks to you guys for the data! Keep 'em coming!

I think its safe to say that if you do run your motor only few hours a
year, like 10-20, a 2 stroke may actually consume less oil. It will
change the more you run it ... Still more data needs to be collected.

A 4 stroke that burns oil, and I was told for cars 1l per 1000 km is
considered no defect (by the manufacturer of course! The owner sees it
differently) will use quiet a bit of oil.

Save you do huge hours per season I doubt a 4 stroke would "use" less
oil than one of the new epa compliant 2 strokes but you might also consider;

(i) The 4 stroke doesn't put oil out into the air or the water, it gets
"changed". Hopefully the used oil gets disposed of correctly, here
that's mostly take it to a garage for their recycle tanks.

(ii) You should at least once a season clean out the oil reservoir on
the 2 strokes (new or old type), the oil in a vented tank absorbs
moisture which creates a sludge in the bottom of the tank.

(iii) The "new" 2 strokes use or at least recommend special dealer only
oils; can be expensive.

I am probably a heavy user here, about 300-350 hours a year in a 12 month
boating season.
I change my oil 4 times a year, using 3 quarts a change and none between. At
that rate I am using a lot less oil than I did with a 2 stroke. It also gets
recycled.
Figure your oil goes in at 50:1 in a 2 stroke, my 60 uses 3 quarts so I could
burn 37.5 gallons of mix but since you usually use a pint per 6 gallon can it
is really 36.125 gallons. That would only last me about 10 hours at a moderate
cruise speed. The oil saving for me is 90% over a 2 stroke. I could even save
more if I used auto oil instead of Merc brand.. If you also add in the actual
fuel efficiency it is greater than that.
I bet the saving is even greater when you get up into the big Vs. His 6 quart
oil change would "mix" about 72 gallons of gas. A 250 2 stroke could easily
burn that on one day's offshore fishing trip.

What's the difference? :-) I mean, are you collecting this information in
order to make a purchase decision? Or, what?
