"The" 2 Stroke Oil Thread
#294
Haha
I am a mechanic myself and it's common sense a little extra oil keeps a little extra lube in fuel system including pumps, also if you had a leaky injector it's not gonna strip that cylinder or other components of it's lube, it will only add ;-) also I know someone that has 520,000 miles on one with original everything including lift pump and this is all he puts in, other that a little k100 to burn any condensation if any at the bottom of the tank!!! Cheers!!

Whatever you do, DO NOT pull the cap off your power steering pump!! I did this morning to check the fluid, and later as I was driving home, the entire rear end and driveshaft passed me on the freeway. I got towed home...........

Well I read this entire post and I believe I've came to a reason of my mileage loss. I was getting 22-24 and yesterday I decided to add some PS with cetane boost to my tank. Today I could barely get 19mpg and that is the only thing that is different. I believe I'm gonna run it down and start back with some 2SO in the next tank. Sorry to kick a dead horse but it was worth the read so I had to comment.

Very interesting read indeed. Coming from a chemical engineer, here is my two cents worth...
I have read through Dieselplace's Lubricity additive study and results as well as comparing the results on the chart provided by 2004LB7. I am highly skeptic about many of the results of the HFRR scores found. I have no doubt that biodiesel and two stroke oil lubricate metal moving parts, but how they were placed by score seems a bit off to me. If you compare additive packages of available additives on the market, you will begin to see many common chemical components, petroleum naphtha being one of the most common. Naphtha is even a major component of two stroke oil. Something you don't see in many of the additives is the use of refined base oil. For example, Schaffer diesel treat 2000 placed higher than two stroke oil yet contains no lubricating oils other than naphtha. Further odd was Lucas upper cylinder lubricant which is literally colorless two stroke oil.
I agree with the use of two stroke oils used as a diesel oil additive to improve lubricity for pre-emissions based engines. Super Tech is manufactured by one of two different companies, Warren oil in the north and Specialty Oil in Texas. Main components is refined petroleum oil and naphtha along with other small additions of anti-smoke, ZDDP and blue dye. Zddp is a major concern as it will tend to plate onto moving parts in the injector assembly and cause fouling of a different kind. Zddp will also contaminate catalytic convertors.
Lucas upper cyl is nearly identical in formulation to two stroke oil, however containing 5-10% less oil favoring a higher quantity of petroleum naphtha. One thing here to note that while naphtha is used as a detergent/dispersant, it also elevates combustion chamber temperatures, thus helping to provide a cleaner burn. This is possibly the reason why mileage ratings increase with use. Lucas contains no Zddp, nor any additives proven harmful to emission equipment.
Stanadyne additives come highly recommended by many manufactures and have received high user ratings for their products. While I did not see any lubricants in their products, I thought their anti-gel component was quite genius. They use ethylene glycol to help prevent gel formation (common concentrated antifreeze). EG is very hydroscopic and will actually combine with residual water in the fuel, allowing it to be burned during combustion. EG also burns cleanly at elevated temperatures, a combined fuel source. If one bottle is used per tank of fuel, this equates to about 2 ounces of EG per tank, I would imagine that a very small amount would be required in the first place. While Stanadyne may not be the greatest lubricant, they offer a really great all around performing product.
Personally, I use Lucas. I use it less for lubricity and more for increased mileage. That and the fact that it is pretty inexpensive, possibly less than two stroke oil, keeps my wallet pretty happy.
