4 stroke care

16 posts in this topic

Not another "winterizing" topic but how often do you change your 4 stroke motor oil if very low hours? I have a 4hp 4 stroke Mercury that I literally use on one to two trips...totaling maybe, maybe 40 hrs all year. Would you change motor oil every year? I typically go through all my "toys" in late fall. Boats all have lower end oil replaced,  parts lubed, trailer lubed, atv oil changes and so on...but I hardly use this motor and wondering how long that motor oil can wait? Better safe than sorry right? Well, if it truly can last a few years with such little use, why change it. I hate spendy extra money and wasting time if its not needed. Would it make a difference if the oil is synthetic?

 

Thanks,

CC

I believe in changing the oil in the fall, just because there could be some contamination or moisture that could cause corrosion over the winter.  But I have skipped it occasionally on stuff like mowers or the power washer.

I religiously change the oil in my outboard every Fall. I also replace the lower unit lube every Fall. My buddy would do his in the Spring, but after I showed him some pictures of split lower units because they had a leak and fluid in there which ultimately froze in the winter, he quickly changed that tune.

I also replace the fuel/water separator filter in the Fall.

To me its good piece of mind to just do these things and hopefully never have issues.

I do lower unit lube every fall and change the motor oil, filter and plugs every other year.  Five quarts of high quality four stroke oil, oil filter and new plugs gets expensive to do every year.

If you don't want to change the lower unit lube in the fall and wait till spring just pull the lower plug/screw and let some drip out. If it looks like milk you have a problem and need to do something about it. If it just drips oil put the screw back in and wait till spring. At least that's what I do and never had a problem yet.

Try 8 quarts like my 150 Suzuki takes. :-)

Regardless of cost, I change the oil. Plugs? I haven't done that yet and this is my 6th season with the boat. I wouldn't think you would need to change plugs annually.

Once a year? expensive?  I hope you're kidding..

Dang, 8 quarts?

Yep! That job hurts a little every time I do it. 2 dang gallon jugs of the Suzuki oil. I think the oil filter is like $15 too.

I probably should pull the plugs this Fall to check them. Would be a good idea. I'm sure those are some fancy plug that is like $8 a piece too. Nothing is cheap these days.

If it's not needed, why would I want to spend the money? Oh...you must be a millennial with endless money. I'm starting to believe much of this is good marketing. Everyone always states "it's cheap insurance..." but why waste money if it's not needed? Briggs and Craftsman's have a lawnmower that you never need to change oil in...maybe they figured it out. How many hrs are actually used on our toys? vehicles now claim to get 10K miles before oil changes with synthetic. 

So which brings me back to my question...are most changing oils every year cause someone said "why not, it's cheap insurance" or is this legitimate? Oils, gas, stabilizers keep improving, costing more...but what's the benefit to the user if we keep following recommendations 20 years ago? (shower thoughts)

If the motor only gets a few hours use every year, only changing the oil every other year or even less is certainly a reasonable thing to do.  Likewise the lower unit lube.    

To me, 40 hours is getting to be enough use I would think seriously about changing it in the fall.   But it is certainly a judgement call.

Clowncolor, I'm not even sure what milianal is.....I'm a 1958 model if that helps.  all I know if once a year to change oil is too expensive, maybe a boat shouldn't be in the cards.......;)

LOL...I do alright.

How often did you change fluids in the '60's?

I said oil, oil filter, lower unit, and plugs gets expensive to do every year.  Probably close to $100 just for the parts.

For sure you don't need plugs every year.  Filters are cheaper online, if you have been buying them at the dealer.   Not sure if there is a cheaper source for the oil like a different brand.   Not sure what your motor requires

Clown Color's 4hp only takes a pint! of oil.    So I would change it if I were him.  Maybe not the filter however, if there is a filter.

    • Glad Lavine is gone! Added nothing but slam dunks to the team. I've been out of town for the past week, so I was very delighted to hear about this trade today.
    • Not unless they ban the toothpick crossbow here too. Takes those beetles out clean.   
    • That's called seasoning. Two years ago I took a trip to Germany and we spent a few days in the black forest where I got to see some authentic old world smoke houses dating back to the 1500's and the amount of buildup on the walls, hooks, poles etc is part of what gives their hams,bacon and sausage their flavor. They use juniper wood for smoking. Absolutely delicious.  But yeah, foil, Pam and other things can help. You can also use a power washer to clean them.
    •   "We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that."   Thanks for making my nite.  
    • Also woodpeckers beat on stuff to mark their territory.   I am pretty sure that there aren't any bugs on my metal downspouts.
    • You will often discover that birds are picking very small insects from decks and other woodwork around your house;  they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on,  perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter. We have discovered  many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think. We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that.
    • And pretty soon there'll be little chinese restaurants springing up everywhere...there goes the neighborhood. 
    • I use the ball of aluminum foil, too. Works well.
    • lay them in the grass over night and wipe off in the morning.  the dew soaks in if it's moist out.  other wise lay them out and place wet towels over them for awhile..
