This message is to let everyone know of a trial I'm doing that goes against all the mantra of single weight engine oil. I'm running Rotella full synthetic T-6 5-w-40 oil in my two stroke 8V92 1993 engine this season. Looking at the specs from Detroit Diesel for approved oil the T6 seems to meet all of them. The critical ones seem to be low sulphated ash and high shear viscosity. I was told that if I made this change my oil consumption would skyrocket. I just made a 2000 mile trip and so far I can detect no consumption at all. At the end of this year I will sample the oil and see what has happened to it over the year. I will post my results on this forum.

There is currently no way to certify new oils for our two strokes and there is no standard way to verify that oils originally certified and approved for these engines still are valid. The reason being that the sole engine used to test these oils has died and will not be replaced. As such there is no way to prove existing certified oils are still good except for meeting the physical specs that T6 also meets. Oil technology has changed a lot recently and I think it's possible that modern lubricants may meet our needs even if unable to be certified for our engine and I'm going to try to find out. If the short term test pans out favorably then in future years I'll pull random (read that as easily accessible) air box covers and inspect the ring grooves on the pistons for ash buildup. We'll see.

Dear Jon, How is your test going?
