Using old car oil in Seadoo?

[Kuzma823]

I like to maintain my vehicle the best that I canand this means that I use full synthetic oil (Royal Purple) in my cars. These oils are made to be able to work for extended periods of time (6k+ miles). My car tells me when to change the oil (based on RPMS, miles, load on engine...normally around 4-5k miles) so I do so religiously so as not to risk any ill effects to the engine. Anyone else who uses this type of oil (or one of its equivalent competitors) knows that this stuff is expensive($8-9 a quart). I am wondering if anyone has used their used synthetic as injection oil in their seadoo.

I own a '97 GS and a '97 GTX and both use the Seadoo Synthetic Injection Oil. Anyone see any harm is by passing the Seadoo oil ($50+ a gallon) and just put the used Royal Purple in instead. I figure I would rather burn "free" full synthetic oil than $50+ a gallon oil.

Note: The "used oil" would still be subject to an inspection before use. Would not use if it contained any foreign materials or was excessively dirty.

You want to run USED engine oil not good enough to run in your car, in your 2 stroke engine that's not able to run a heavy 4 stroke engine oil... Oh yeah, that makes sense. NOT!
Even new 4 stroke engine oil can't be run in a 2 stroke engine.

theres no "crankcase" oil in these 2-strokes. the oil in your resivoirs' of your skis', get injected into the manifold along with the gas, coming thru the carbs. That "royal purple" wont burn/mix with gas.

I don't even know where to start on this one...

1) You don't want it in your car anymore... why do you want to put it in your Sea-Doo?

2) most synthetic oils don't burn under normal temps... so it would go out your pipe. (bad for the environment)

3) It's full of carbon soot, and microscopic metal flecks... can we say sand paper??

4) it was never meant to be mixed with gasoline... and it may just go to the bottom of the fuel tank if used as a pre-mix. (or turn hard)

5) Wrong viscosity for an injector pump.

6) Was not developed as a thin film oil.

7) it has additives that were meant to neutralize leftover hydro-carbons... and they don't react well with raw fuel.

8) It will contain sulfur compounds as a high shear/pressure lubricant that won't play nice with the chrome steel of your ball bearings. (good for the piston skirt though)

9) contains long chain polymers to create the multy-weight or "W" rating in the oil. Those don't burn, and can actually melt, and redeposit in cool places. (like your rings when you shut down)

Do I need to keep going??

You don't have to take my word for it... run it, and let us know how it works.

FYI... Before opening my shop... I was an R&D chemist.

But!!!

I agree, don't use it in the ski, BUT I like how you are thinking. "Why not recycle it by burning it through another engine?"

But it won't work that way.

Good idea, though. Glad you asked before you did it.:cheers:

How would your oil be inspected for metal particles floating around?

Still, it might not be too bad. SBT can always use the work to repair your motor. Some technician might have some work to do also.
