( Deere's Application Guideline 18 has more to say about use of aviation fuels, including this: PowerTech PSX, PVX, PWX Engines \(4.5 L / 6.8 L / 9.0 L / 13.5 L\) \(Engines with John Deere supplied Diesel Oxidation Catalyst\) Aviation Fuels All Not allowed. Aviation Fuel has sulfur content levels greater than 0.002% \(20 ppm\) and are not allowed for use with John Deere engines with Diesel Oxidation Catalyst. This includes fuels such as;...

I know of all the points you made regarding the engine characteristics. I guess we are trying to have our cake and eat it too. I want the power/torque of the 750 engine but I want it to rev and handle like the lighter 600 engine.  

( Kev A bigger engine is normally slightly less responsive than a smaller engine as the parts are normally heavier caising higher inertia. The further the weight is removed from the axis of a rotating part the greater the reduction in inertia and gyro effect. A heavier bike and stronger gyro will both contribute to slower transition. A heavier crank contributes to both. The bigger motor, even though less responsive on a free rev will have more...

I have to admit that sabotage did occur to me too. It does happen.

( ... you'd need to get all your information from a bloke in the pub. , )

If the jacket water heaters are convection type, then yes, they can degrade the corrosion protection.  If you pull a heating element out and see a white to tan deposit, and loose debris in the bottom of the tank, then your tank heaters are affecting your coolants corrosion protection.  KIM Hotstart sells smaller jacket water heaters with small circulation pumps, actually work better than the convection...

hajiali-       I would be pessimistic you could build one in a reasonable amount of time for a reasonable amount of money.          If you want this for research purposes, get in touch with Westport Innovations and explain what injector you want.  Make it clear that this is for research...

gentlemen thanks for your tips. we will take a close look at both the block heaters and the electrical bonding on the engine block & rad. M6

Like anything, there is a large gap between what you can get away with for XXX operating hours, and what the system in question has been validated to work with for its specifed life.

OK guys, hold back, snake oil it is then.  I knew I could rely on you lot to put me straight ! To put a slightly different twist on the discussion, whats the best way of adding some sulphur back into ULSD for the old timer motors that need this for lubrication ? Once you've got the sulphur levels back up (is there a limit ?) do you need to consider what spec of sump oil you use to cope with the new sulphur ? Or is there...
