Has anybody experienec with Synthetic Motor Oil? To date I have always used mineral oil with Triumphs. I am now having a difficulty to find this type of oil without paying exorbitant price. Many years ago, one warned me not use sythetic oil, as it is not made to be used with our engine's large tolerances. Perhaps after so many years something has changed for the better. My type of driving does not need anything special like Duckams etc.
