ozzietriker Posted March 25, 2014 Share Posted March 25, 2014 G'day all, Is there a substitute oil for "Aeroshell Oil Sport Plus 4" that meets the specification for use in a Rotax 912 ULS engine and an oil I can easily get from a motorbike or car shop? I'm finding it very difficult and expensive to source this oil in Perth WA, if there are any substitutes out there that meet the Rotax spec I'd be grateful to hear from you. Thanks Andrew Link to comment Share on other sites More sharing options...
microman Posted March 26, 2014 Share Posted March 26, 2014 Some of the guys here use Mobil 1 - its a fully synthetic oil, but the required spec, and easily obtainable. Link to comment Share on other sites More sharing options...

Neil_S Posted March 26, 2014 Share Posted March 26, 2014 Hi Andrew, Shell Advance VSX 4 is pretty easy to get from motorbike stores. We have used it for years in our Rotax 912A. It's on the list (2 different viscosities - I am pretty sure we use 15W50). Cheers Neil 1 Link to comment Share on other sites More sharing options...

alf jessup Posted March 26, 2014 Share Posted March 26, 2014 Problem with using motorcycle oils ect is oil companies don't have to inform you when they change the additives in them, aircraft oils they do, so what you buy this month may not be exactly the same in 3 months time.

The Castrol change is example. They changed the blend and IMO should have changed the name of the oil brand. I've just sent an email to RAA (Darren) suggesting an article in the magazine for the Rotax owners and others information. I'll chase up the aircraft oil brand. Do you use EVVA 15w50 or Skydive areolube 10/40 oil? Thanks for info. Mike Link to comment Share on other sites More sharing options...

facthunter Posted March 27, 2014 Share Posted March 27, 2014 There's probably a lot of oils that would be OK for the motor but the redrive shares the engine oil. Not all engine oils are suitable for gears (and the dampening clutch) It's many years since engine oils were suitable for gearboxes, generally.

Downunder Posted March 29, 2014 Share Posted March 29, 2014 I've read that semi-synthetic only if running avgas as the lead is not kept in suspension with full synthetic. Link to comment Share on other sites More sharing options...

Shell changed the formula (and renamed it) and Rotax took it off their list. Link to comment Share on other sites More sharing options...
nong Posted March 30, 2014 Share Posted March 30, 2014 Rotax recommend motorcycle oils as a general idea, because these engines have similar lubrication requirements to motorcycles. To be precise, motorcycle engine oils must also lubricate the primary and secondary reduction gear sets. Downunder's comment about not using a full synthetic with avgas is confirmed in technical papers released by Shell. Link to comment Share on other sites More sharing options...
