115 4 stroke

[Tonyc]

Any problem with using Penzoil 10W-30 oil ?<br /><br />How often should I decarbon the motor, I was told this should still be done even though it is a 4 stroke.

Howdy, Tony.<br /><br />What oil does your Owner's Manual call for? Pennzoil is good oil, but it should be the weight recommended by the maker.<br /><br />I don't decarb 4 strokes at all, especially EFI 4 strokes. They don't burn oil, only gasoline. <br /><br />Good luck.

Manual says Merc 4 stroke or a Premium grade 4 cycle engine oil. Not tryin to be cheap but does the Quick silver oil have anything special in it.<br /><br />My dealer told me to Decarbon but my theory is like yours. It ain't burnin oil mix.<br /><br />Good runnin motor though I change my oil every 60 hours.

Re: 115 4 stroke

2002 model I have seen your posts. I just changed my oil this weekend didn't see anything unusual as far as what you are describing.<br /><br />I do however understand your frustration and wish you luck. <br /><br />Let us know how you make out I would think any amount of water in a crankcase would be death to a 4 stroke motor of any kind.

Were it my motor, I'd go synthetic right after break-in (IMHO). But while the motor is still under warranty, it's "wisest" to use their brand of oil. If problems arise, they can't blame somebody else's oil and deny your claim.
