As longas all four wheels are on the ground, it'll be fine. However, certain 4WD and all AWD vehicles can get their transfer cases destroyed if only two wheels are left on the ground. Jeeps and Subarus get destroyed all the time this way. Ever heard the story of the GTR that got destroyed doing that?

clutch, with an auto there's still next to no load and the planetary gears will just spin away. Not generating much heat I'd say. Magnum spot on tho', on only two wheels then there are LOTS of loads going on in the centre diff that'll generate oodles of heat !!

BUT does remind me that auto gears often run pressurised lubrication Without engine running there could be major wear issues !! So, I've changed my mind. It's now a "depends" on how far, how long and how the box is lubricated -- so safer saying NO

Agreed, it's a rare breed of auto trans which is able to maintain proper lubrication without engine running. But I am not sure of the "automated manuals".

Correct! There's precious few which can be. You either needed to drop the drive axles or raise the drive wheels off the ground. Search a little though and a lot of RV websites will list what vehicles are capable of being "flat-towed" with an auto trans.

On an unrelated note: why can't rotaries run synthetic oils?

he might have been cheaper off just building the Protar 1/9 scale kit, like I did many moons ago.

Wow, that's excessive attention to detail. The fact that it was so difficult to replicate even today shows of the craftsmanship of the original.

Man, Soichiro Honda was a genius.

Was lucky to hear the original beauty rev to 16K at Isle of Man a few years back on Honda's 50th anniversary. Lots of their key race bikes were specially brought from the factory and run in public. Each bike had it's own mechanic

Would love to see this and maybe it will make an appearance at TT time and get revved out to it's max ( beyond 20K )

Rotaries that use the lubrication oil to keep the tips lubed can't run SOME synthetics as they cause too much carbon build up. Carbon build up can destroy a tip. The term "synthetic" is abused tho and so I run the race car on FUCHS race oil which is labelled "Synthetic" but is perfectly safe ! Go figure. Opie oil dealer had an excellent write up on the differences for us rotary runners. If you really need tech info I can maybe dig it out ??

and on the

Either that or the computer is having a hard time re-learning its running strategy. Usually should pretty much get there after an hour's worth of driving, though. Maybe pull the plugs and make sure there's no undue fouling or anything.

Fuel pressure ok? Does it feel like it's starving, choking or just not firing?

LPG has higher energy density and higher octane than petrol, so when you switch back to petrol, the ECU will tell the engine to run leaner, which will only be made worse under load. Completing a drive cycle should get it back to normal. Any problems with your fuel system will compound the problem too, so change your fuel filter while your at it.
