Changing 2 cycle oils, 1998 GTS.

[kybishop]

Just recently purchased this 98 GTS. It has Quicksilver TC-W3 2 cycle oil in it and I want to change it out. Going to go with the Mystic JT-4 Synthetic, details here. http://docs.mystiklubes.com/msds_pi/M20077.pdf and

Is there a write up on how to properly change oils out? I know I need to drain the old out but need to know how to go about getting it out of all the necessary lines and how to refill without doing damage.

Thanks for any help.

I don't think there is a write-up on it... but it's not hard.


If you have a suction pump... use that to get the bulk of the oil out. if not... follow below.

1) Pinch the hose at the oil filter.
2) Remove the hose that the filter, and put a sutable container under it, and remove the pinch.
3) Once the tank is drained, remove the hose under the manifold. That will make a mess, but you need to get the oil out of the RV cavity.
4) let it drip for a while, and make sure there isn't any oil hiding in the corner of the oil tank.
5) Replace the oil filter, and put the hoses back on.
6) Fill the tank with the new oil
7) Open the bleed screw on the oil pump, and let the oil flow to get the air out of the feed hose.

That's about it. More or less... just drain and re-fill.

BUT.... I would also recommend replacing the small injection hoses if they show any sign of deterioration. If you do that... after you bleed the feed hose... start the engine, and let it idle, while you hold the pump arm in the "Full" position. You will see the oil pulse up the hoses about 1/8" every 2 seconds. It will take about 30 seconds for the small lines to fill.
