Two Stroke Oil Update
There are two types of outboard motor oil to suit the two types of outboard motor -
Two-stroke oil is designed to be mixed and burned with the fuel in a two-stroke motor, where the mix is forced thru the bottom end across the crankshaft and bearings, providing lubrication for the rotating\reciprocating assembly, then burned in the comustion chamber.
Without leaving harmful deposits in the cc and exhaust.
Four-stroke motor oil is designed for crank, camshaft, bearings, lifters, pushrods, rocker arms, piston skirts, etc, but Not to be burned in the combustion chamber, just like passenger and utility vehicle motor oil.
Two-stroke oil is designed to be combusted with fuel - four-stroke oil is not.
For synthetics, always read the manufacturer's intended-use specs on the container, or\and go to the website for the MSDS and specifications

Today I got back from a 1600 mile round trip to New Mexico, and ran the 2 stroke oil the whole way. Two fill-ups were around 36 - 37 gal and I added 16 oz each time. Last time was only 18 gal, so didn't add any. In addition to being a lot quieter, I got a steady 12.7 mpg, up from 10.something a couple of weeks ago. I'm pretty well convinced, and will keep using it.
BTW, I figured out the correction for my 19.5" tires - the GPS reads 64 mph at an indicated 60 on the speedo. Works out to 13.5 mpg, which pleases me just fine. At 70 mph, I'm turning about 1800+ rpm. Just right.

i will keep using it as long as i have my truck
I hadta go back and check on myself. :-) I'd used some fuel before adding oil, so drove from Palm Springs to Kingman, AZ before filling up. It took around 25 gal., so added 16 oz of oil. Then when coming home, stopped about 30 miles south of Santa Fe, filled up with 37.37 gal and added 16 oz oil. Topped up in Kingman again - 36.25 gal and 16 oz oil. When I got near home, topped up in 1000 Palms with 18.34 gal, and didn't add oil that time. I'm completely sold - doesn't matter why or howcum - it's still obviously a Cummins diesel, but the sharp edge of the noise is gone, it's quieter and mileage is better.

I was able to scam 30 litres of bio off a member at our get together today. I've only put on a couple km since filling it up (works out to about 20% bio in the tank), but its already quieted down the pump noise, and has a different smell to the exhaust. We'll see if there are any mileage changes. Bad time to try, as winterized fuel will be coming in around this time.
I've been running it for the last 10K miles and no problems with it. It is a lot quietier, you d ogain about 1-2 MPG from it....
What I'm using is...

Trust me when you skip a doze of forget the truck lets you know! KNOCKING...
It nice to make it quietier...
80:1 - 120:1 mixture is what I'm running... Basically a quart for every 20-25 gallons of fuel.
I've even tested this out on a 1997 Chevy 6.5L Diesel with excellent results... The Chevy use to trip the SES Light (Service Engine Soon) and miss randomly when hot also the knock was quite loud. Not any more... Starts easy, runs quietly, and doesn't miss any more...

To solve the lubricity issue...run Bio20%, if you can get it. Talk about a smoother idle!!
A little higher than diesel but cheaper than added cost of 2 stroke. It's that way around here anyway!
Major increase in mileage from adding 2-cycle oil is difficult to understand and, IMO, should not be expected.

2 stroke oil
what is the deal with the 2 stroke oil you guys have caught my attention. i have 137k on my truck and will do anything to make the vp-44 last longer. is this practice safe or will it harm the truck in the long run. i work in ems so i dont make lots of money so i dont want to do anything to harm the truck..







thing off!
