2017 Rotax 250hp Oil Change

[Liberty195]

New to forum, sold our 96’ Challenger 800 with single 787 and just picked up a 2017 Scarab 195 HO with a single 250hp Rotax.

I’ve read threads but saw conflicting responses. Is T6 full synthetic 5w40 the right oil for this engine? Filter is 420956744?

There is a bulletin out there about the 1503 saying to use semi synthetic and not full synthetic but I’d read here that folks are using T6. Thanks

The official correct oil is either the XPS semi-synthetic blend oil OR now their new fully synthetic XPS. The key for the full synthetic is that the oil has to be JASO-MA2 certified. From a quick google search, the T6 you're mentioning is not unless my google Fu is failing me.

Frankly, is there a reason you can't just buy an XPS oil change kits? It comes with the filter too and the right amount of oil. I don't even know what the filter number is because I've always just bought the kit.

Thanks!! If T6 was being used by many folks I’d be glad to use it, I use Rotella in my diesels on my big boat, $50 saving is $50. But your right and I’ll plan to use one of the oil change kits which seem to now come with full synthetic…. And the filter and rings which is nice.

That was part of my confusion. Reading to not use full synthetic in these engines, then seeing the kits come with full synthetic. Likely that is because the xps additives are in there full synthetic as you mention. Thanks again!

The full synthetic is new for 2024. The semi is being discontinued. Presumably because BRP now has an XPS oil compatible so they can make money off of it. Lol But yeah, I'd stick with that certification personally. I'm all for saving a few dollars... But that box is damn convenient.

One other question. Can I warm her up in my driveway on the flush hose port, 10 min or so, extract, and then re fill? Or do I need to crank a few times after extracting to get more oil to the bottom? Hate the idea of cranking or starting while the sump is empty! Thx

No. Ok if you're new to Rotax, you really should go read the operator manual available online. There are very important instructions in there.

In short, you cannot run the engine out of water for more than 2 min EVEN if you provide cooling. The carbon seal is NOT cooled with the hose. I recommend keeping all out of water run times under 1 min. It's enough to warm up the oil just fine.

Second, do NOT apply water pressure to the exhaust flush port unless the engine is running. The order is important

1. Engine on
2. Water on
3. Water off
4. Engine off.

I sincerely recommend reading this before doing your oil change yourself.

Thank you! I will read the manual per your link first and heed your recommendations. Appreciate it!!

Just an FYI, there's also a Scarab section in the forum. Posting there but also searching it may prove very useful.
