mixing oil?

[wholf09]

I was using Bombardier XP-S Synthetic oil in my 97 spx.I normally would not mix the oil but they do not carry the XP-S where I live any more so I switched to CITGO low smoke supergard sea and snow .On the back it says that it is synthetic and that it will run in Bombardier skidoo. seadoo.

My question is when I took out my ski it did not seem to run at its peak. I ran about 4mph slower and maybe I was just being paranoid, but I think it was running a little ruff. Could it just be the difference in the oil quality or can I not mix the two synthetic blends. I know you are not suppose to mix synthetic and mineral but what about two different synthetic
ics.

Rule of thumb...I never mix any different brands of oil as everyone has their own blends of additives...as long as it is the same API you should be ok. Here is what seadoo recommends;

Use High quality low ASH API TC Injector oil.
Do Not use NMMA TC-W, TC-W2 or TC-W3 outboard motor oils or other ash less type 2 cycle oil. Avoid mixing different brands of API TC oil as resulting chemical reaction will cause severe engine damage. Never mix Mineral or synthetics oil together.

Never use fuel containing more than 10 % alcohol,( Methanol or Ethanol) as severe damage will occur. The minimum of 87 octane is recommended for most engines.

Just be sure it is in the same range of the recommendation and you should be ok.

do you think I could mix these safely.

I see

Yes, Yes, Yes, .....I see now. The homogenized viscosity of the internal density is directly related to the proportional weight of the maternal boiling point of the sulfates before vaporizing. Therefore, if you look at the equation of ASTM D 2160 minus the flash point of the H-value of the cST 7.4 typ, then you'll notice the propensity of a thermal bond, only usable in the space shuttle engines thrusters.
The observations of the Gravity of ASTM D 4052 and the boiling point of .93, lead me to believe that the color coordination of the Total base is reliant on the weight of the specific gravity of the based mineral of the coalesed oils.
Hence we give scientific data to the idea, that this oil will not float from the wheel bearings while the shuttle is in space, orbiting the earth.
....I forgot, now what was the question:rofl:
