CastrolPOWER1 ULTIMATE 2T Motorcycle Oil 1L

Bit of a weird use case, but I own an RX-8 with a rotary engine, which is recommended you add some 2 stroke oil at fuel fill up time in order to prevent excessive wear to the Apex Seals. This stuff is relatively inexpensive, lasts me 8 or 9 full tanks, and mixes well with the fuel. Recommended for my Rotary brothers/sisters!

Fully synthetic high spec 2 stroke oil.

(Tl:Dr at bottom) Added to diesel fuel. Quite low viscosity (runny) for 2t oil. But then this is cutting edge, modern, high spec (JASO-FD) fully synthetic oil.It's not at all like the old gloopy stroker oil which you can buy cheaply in lots of places. Has made a world of a difference. Its a bit pricey where I bought mine, but it's great stuff.Burns cleaner (less smoke & residue) is easy to ignite and is more slippery in my test setup than any other two stroke oil I tried.. and there were quite a few of them!Strong detergent effect so cleans what it makes contact with.Smoother running and pulls better, effect noticeable in first tank @ 200:1 ratio.Summary/tl:dr: great stuff, but a little dearer than competitive products. Works great for diesels. Slippery, mixes wonderfully and stays suspended in fuel, burns FAR cleaner than the diesel itself. Cleans fuel path inside engine and out with prolonged use. Doesn't hurt catalyst, common rail, exhaust or emissions systems, injectors, hoses, fuel pumps or high pressure injection pumps. Does not turn fuel red or pink at 200:1 ratio. Theoretically boosts cetane rating.
