Amsoil has a straight 30 weight oil for two stroke detroits. It is supposed to result in better fuel mileage and with the bypass filter and oil analysis oil changes are very rare.
On their web site they have satisfied customers, one in particular who has not changed his oil in some 400,000 miles with good results!
It is about $20 bucks a gallon but the savings in fuel and wear and tear sound inviting.
Has anyone tried it?
If so with what results?

since most DD Non tubo engines burn a gallon every 1500 miles it sounds a expensive. |

At the rate mine uses oil, it changes itself automatically every 15,000 any how.

OK...."Changing oil IN a detroit". Figureing the amount of oil they sweat. The amount they eat. Just how much original oil are you changing? Feel guilty, drain a gallon pour it in the fuel,top her off. That should maintain the addative package.
Of all the engines I have seen that pucked there noodle, (see thru block). The reasons were because of valves,rocker arm,cam, cam drive,piston
turbos,injector,over rev. Driver forgot to check oil,for a month! Drain plug fell out? Oil filter blew off or, o-ring from old filter still on adapter with new filter. Never pulled a dip stick that had oil on it and have an oil failure.
I would change oil if I had to store it for months (plug the breathers). thats it. ALL oil becomes fuel. I've been recycling for years.

I better check my engine to make sure it is a detroit 6v71 because it has not burned or leaked any oil in a thousand of full throttle,
hot summer vermont hill climbing,
pulling my beer,food,wife,kid, and fat belly
24,700 pounds total weight,
highway travelling,
on the govenor driving miles.
Now lets see---hmm-- Yup it is a detroit two cycle 6v71 with n-75 injectors and a two speed (yuck) VH-9.
Are they supposed to leak(sweat) and burn(eat) oil like i was refining it in my Massachusetts back yard? (don't tell Mitt he will tax me some more)
By the way it does'nt smoke(much) or rattle but it sure stinks--heheheh

Steve -
This question (synthetic oils) comes up periodically on this and other bus BBSs. General consensus is it's ok for tranny, but not for motor.
DDA recommends straight 40wt, CF-2, 1% or less ash content oil in the two-stroke engines. Here's the link for the scoop, straight from the folks who should know: http://www.detroitdiesel.com/public/svc/lof/7se270-9912.pdf
My suggestion would be to email Amsoil's tech support dept, include the link to DDA, and ask them if their oil meets the specifications outlined in this publication.
When you get a response, post it here to share with others. . .
HTH,

Steve--how'd you do it?! The 6V71 at work drinks about 2 quarts of Delo SAE40 per day. It seems to be about half leaking andf half burning. |

Ok...Steve fess up. You have a dry sump and have dipped the engine in EPOXY .All the DD I have been around never had rust ON-NEAR-OR-AROUND them. Even the Butt connectors on the tail light wires driped oil.
On a serious note if the oil's addative package does not have detergent/solvent, varnish will form and make a great seal. If the oil is high enough detergent, all the gaskets will have a 'halo'of oil around them.

Seriously-- I run straight 40 weight and so far over a thousand miles and no drop on the dip stick.
There is a pulley on the front of the motor that seems to stay wet with oil but the rest of the motor seems dry with the exception of some dripping out the air box drains only when cold.
This was a well maintained transit with oil and filter changes including the big bypass sock filter every 6,000 miles.
It has about 385,000 acording to the computor maintenece printout i received from the transit company.
Now on the oil, it is rated CF2 which is the correct rating for detroit two cycle and they make a straight 30 weight but i am not sure on ash content.
I will check and post any info.
thanks---steve |

AMSOIL Diesel Oil is recommended for virtually every diesel application, including truck fleets, mining, earth moving, farming and stationary engines. In every engine tested (including Detroit Diesel, Caterpillar, Cummins and Mack), the advanced 12 TBN additive system of AMSOIL Diesel Oil significantly reduced ring wear, cylinder bore polishing, cylinder liner wear, oil consumption, piston deposits and ring breakage.

OK..... So you don't deny you dipped that Yamaha in EPOXY.
Seriously if you run a lubricant that is say as good as Mobile Delvac or Shell Rottela from 20 years ago you're safe. And remembering that Mobile 1 was NOT up to spec for any diesel made after 1956!!! I think it has been updated?
I mean no insult. The 53/71/92/ DD are 1960's technology. The NEW engines NEED the best API "C" (C-compression) service level they can get. The temp. of the pistons(oil cool spray) and the shaft on the turbo and the followers on the cam and add in exstended or NO change intervals. All are the areas that make up the light years between a Series 60 and 8V92.
OR ( lack of sensitivity )its just a waste to put 100 octain and Amsoil in a Lawboy. Its just not cost effective! Your hearts in the right place,JUST put the AMSOIL in the wheel bearings,trans and diff.

Stevebnut. First, I'm am no DD expert. One of the things to look for when you appear to not use oil is that the oil consumed is being replaced by fuel oil.
When the oil level increases, it is easy to tell something is wrong. If you have a fuel dilution problem that is just maintaining your level it would be harder to detect. If you dilute the lube oil enough, it can be di$$aster.
I hope you just have an exceptional DD and that it continues to be so.
Good luck. |

Don in WA:
I will second that. In sail boating (small diesels that get only 40 or 50 hours a Year) it is not uncommon for the engine to "make oil". In that case I understand that it is usually the injector pump with bad seals leaking fuel into the crankcase.
The good part is that Diesel is a relatively good lubricant (not so for gasoline). You do loose viscosity (and oil pressure)...
You never really know if you have “normal” oil burn and leakage: so I just take note of oil pressure, feel the oil on the dipstick, and change it often.

I have run delo 15-40 in my 8V92 for several years with no problems. It starts much easier when cold and cut the oil consuption by 40%. I know detroit says no but I have several friends with commercial trucks that have used it for years and swear by it

Steve
This weekend I changed the 04 671 oil to Royal Purple syinthetic 40 wt.I am told by R.P. this oil has been oked by DD to use in a 71 series engine. They say the engine will run cooler/it will not burn as much oil as the rings will be clean and will work as they were designed to not only expand and contract but also rotate circumfretaly.Also I will experience better fuel milage.
I will let you know how it goes.
