[QUOTE="Adie"] in >> > there, cos it smells all Castrol R when it's running but the guy >> > said it was a synth oil he was using. email received and he says TTS which is available from my local halfrauds. I'll pop in this week and buy some and see if that offer for screwdrivers includes this.[/QUOTE] So the sticker that Andy mentioned says 'Castrol Racing 2 Stroke', which to me implies the Power 1 Racing 2T, the guy says TTS, & Lozzo says it smells like castor based. Confusing! I've emailed my New Best Friend[1] (Automotive Oils Technical Advisor at Castrol) to see what he reckons. [1] MV back brake locked up solid on the way to Avebury due to moisture in the fluid expanding when hot[2]. Matey stops to see if I need a hand, & gives me a Williams F1/Castrol branded Leatherman to use as I didn't have any tools with me. He insisted I keep it, which was a good job as it locked again on the way home. [2] Lesson learnt - brake fluid doesn't keep even when put in a wine bottle & all the air sucked out with one of those vacuum pump things[3]. [3] Which normally I wouldn't bother doing, but this was SRF which is bastard expensive (50 quid a litre).
