Only if it's a Detroit

OUR CUMMINS ENGINES ON THE BOAT USED TO HAVE AN OIL FILTRATION SYSTEM THAT MIXED THE USED SUMP OIL AND PUT IT THRU THE FUEL SYSTEM TO BE RE-BURNT.THE RATIO WAS 60LTR SUMP OIL TO 6000LTS DEISEL...AFTER HAVING THE SYSTEM FOR 6 MTHS AND SEEING THE CLOUR OF THE FUEL FILTERS AFTER 100HRS RUNNING, AND THE FUEL THAT DRAINED OUT OF THEM THE SYSTEM WENT IN THE SHED NEVER TO BE USED AGAIN..
I WOULDN'T ADD OIL OF ANY SORT TO MY FUEL SYSTEM,EVEN IN THE SMALLEST AMOUNTS..

CHEERS EAN

Ean,

Your caps lock is on.

How much oil do you have to dispose of if you do not burn it in the engine? Do you use oil condition to determine when to change it or do you just go on hours? Do the engines have any bypass filters like a centrifuge or dunny roll filter?

Main Engine holds 75ltrs, and runs the standard 2 cummins oil filters with a dunny roll type filter that was fitted aftermarket..We take oil samples but oil /filter change interval is 500hrs/ except dunnyroll,every 1000hrs
Gen-set holds 25lts and has standard filter system, take oil samples but change oil/ filters every 250hrs..
Gbox every 1000hrs.

Have a 1500ltr waste oil tank on board, which is pumped out in town at the end of each season.
Oil used is Caltex Delo 400..when we used Shell oil we had all sorts of consumption issues, even when 1 engine was new, but this oil seems good.
Usually by the time the oil samples get done if anything is on its way out its usually failed before the results are back, but the insurance company loves the fact we do them.

Cheers Ean

My tuppance worth.........Diesels burn oil............peanut oil, vegetable oil, mineral oil (diesel).......If they mucking around with the diesel and removing elements that affect the performance / maintainance of the engine then it makes sense to add something to restore these properties....Two Stroke oil sounds good to me........although I am not going to try it...................as all my vehicles are petrol

They (as in the refineries) removed the nasty sulphur which contrary to popular myth has no effect on diesel lubricity at all, in fact it's nasty stuff all round.

What does happen is that during the process of removing the sulphur some of the aromatic components that do contribute to diesel lubricity are removed too, but, by law all diesel sold in this country has to conform to a minimum lubricity standard (it's a physical scar test) which IIRC is at least as high as it was back when we had 500PPM sulphur diesel, then we moved to 50 and now 10PPM sulphur diesel.

To achieve this the refiners add a lubricant to meet the Oz specs, so a lubricant is added before you even buy diesel.

Hey Ean,,
if its not a secret,,
what model Cummins?
