pattayadon Posted July 18, 2017 Share Posted July 18, 2017 You shouldn't have any oil consumption. Even for a 1996 Toyota w/200k+ miles it should be minimal. You probably need a ring job or you have a high-speed leak somewhere. Good luck with that. Link to comment Share on other sites More sharing options...

Did I read someone brought the racist card to the motoring forum.... And you would also say the same for (manual) gearboxes? Don't use synth? (have looked for synt gear oil in BKK (Worachak area) can't find normal syn gear oil, half syn is available.)

Engine oils work around 230F. Auto trans is a different kettle of fish, it is a work place using engine HP, sees temps probably 175F and up..

Nor me, but an auto trans fluid exits the trans and goes through the bottom of a rides radiator where the water is coolest or has an air cooled cooler usually strapped to the rad so the fan pulls air through it then returns the fluid to the box sump.. The only rides I have dealt with where the oil gets really hot is transverse engine and box combo's where the box uses the engine oil..Real Mini's for instance...

Yes, actually I was. The gearbox is a manual, 4-gear, from an about 30 year old Mazda 6-wheeler truck. Very popular in longtail boats and in larger taxi boats. 4-gear yes, but reverse, 1st and 2nd are removed, the 3rd gear is flipped and used as reverse. Guess the original engine would be a modest 4-pot diesel, say 100-120 horsepowers with rpm, max 3000? My engine is 260 hp at 5400, so the box has something to chew on. Not running flat pedal all the time of course, hardly ever. But in general boat engines works much harder than car engines, a boat is ALWAYS running uphill, relatively higher rpm than cars, only the highest gear available.

transam Posted July 19, 2017 Share Posted July 19, 2017 It seems in the past using syn in a manual box was a no no cos it was toooo slippery, but the big names have done their stuff to provide the best for a manual box to deal with extremes, a syn oil.... http://www.castrol.com/en_gb/united-kingdom/products/cars/manual-transmission-fluids.html Link to comment Share on other sites More sharing options...

Actually the spinning gears is what sloshes the lube around - the more gears spinning the more lubricant bouncing around....

Above, pipe (with flexible hoses) through box and water/coolant in pipe might be an OK idea, need give that some thought boat is not light duty, its very hard work, much harder for the power train to drive a boat than to drive a car, note, boats ALWAYS run uphill (no flat terrain and no downhill for boats), always high gear, relatively high rpm over prolonged periods compared to cars Link to comment Share on other sites More sharing options...

I occasionally wonder why the air-cooled setup of the Volkswagen Beetle was not adopted by more car manufacturers. One less fluid system to leak, although there were presumably other variables which cancelled out that benefit. Link to comment Share on other sites More sharing options...
