Hi David, I'm also using DTE light in Wrens (SS & 44) with no problems whatsoever. Look up the company Lubes Direct located at Penrith NSW, a Mobil distributor.

Last time I bought it it was about $90 including delivery for 20 litres. The only down side with the DTE light is the colour, it has none! This makes fuel levels a little harder to see.

I did try Castrol TTS oil 2 stroke as recomended by Wren but I do not fly as often as I would like & had problems with gummy bearings which the starter would struggle with on the first start of the day. - John.
