If you're having trouble finding Mobil DTE, see if your local Chevron supplier has their ISO VG32 equivalent product "GST 32". It is similarly priced ($58/5 gal here), non-carcinogenic, doesn't turn brown in the sun, with no foul smell/eye burn when running.

I've used 5% GST 32 exclusively in all my turbines for the past 2 years in Artes Rhino, Eagle, Falcon PST 600R, 1300R and JetCat Titan, P-60 with not one single issue.
