6V92/8V92 engine oil

[warbucks13477]

I have been trying for the last week to get a supply of Rotella T 40W for my 1985 PT40 and have been having a problem finding it. Finally got 4 cases of gallons from a friend of mine that has a diesel repair shop for $13/gallon. Was wondering why all of a sudden it was hard to get here.

Have been doing some hunting on the Detroit Diesel yahoo site which I have belonged to for quite some time and may have found out why.

This site http://tejascoach.com/tejasoil.html has some interesting information about Detroit Diesel oils. Rotella T meets all of the DD specs of a CF2 grade oil with less then 1% ash right on the line with 1% ash content.

Delo 100 on the other had is also a grade CF2 oil that far exceeds the 1% ash content with a content of .76% or 24% better. Guess I will start using Delo 100 after this.

Another good thing on the site is the reason you DO NOT use multi viscosity oils and the results if you do.

Thought other members many enjoy reading this and also the Detroit Diesel group at .http://autos.groups.yahoo.com/group/DetroitDiesel

Hugh we dont have an O'Reillys in NY or even close. If you put T40-1 in their search function it will then ask you for your zip code which mine is 13477. You come up with NONE AVAILABLE. In any case that is not the way to find motor oils or fluids because of the cost and problems shipping them. Oil is heavy.

I got my 12 gallons of rotella t today at $13.84 a gallon a $.84 increase in two days. Go figure that with the cost of oil going down I got an increase in the cost of motor oil?????

Because of the economy even the distributers in my area are not stocking oils that are not rapidly used.

Was in my friends diesel repair shop when I asked him to order the oil from his bulk supplier and a customer there started asking questions. Asked me what the oil was for and I remarked a DD 6V92 engine. He smiled and said to me "you dont obviously keep up with the times do you?" He then went on to explain that he now uses 15W-45 multi weight in all of his DD from the series 60 to the 6V51, 6V71 and 6V/8V-92. He told me it was better then straight 40W oil. When I informed him of the differences between the oils and why he should not be using the multi viscosity oils in his 2 cycle diesels he almost choked not realizing the damage that he may have already done to the engines. My friend interceded and told him the same thing and the poor fellow was not happy.

But I have seen BB owners of the 80's and90's coaches with DD 2 cycle engines that were using multi weight oils in their engines. In fact when I bought my 1985 PT 40 in Dallas Texas there was a sheet in the blue box saying to use the multi weight oils in it........and it was from the factory . Now figure that out?

From now on I use Delo 100 40W and not rotella T 40W

Tom,

Here in PA, many of the old 2-stroke owners that I've met use TRC (Texas Refinery Corp) Pro-Spec DD Motor Oil. It is sold through distributors mainly to fleet owners. You can go to their website http://www.texasrefinery.com/ and read up on what they offer. There is probably a distributor in Syracuse. I've been using it for about 30K miles and I'm burning less than I did with other 40W brands- usually about 4 to 4.5 gallons per 10,000 miles compared to 5 or 5.5 previously. I get the oil tested every 10K miles and the TBN has remained intact after use (probably due to low-sulfur fuels more than anything). Other trace metals have been withing or even below spec on wear.

Tom

I used 400 last year. Based on what I read from tejas I should use the 100. When I do the oil change I will go with 100 not that I know the difference and that I can get locally through Oreillys. I have a feeling this subject could turn into What are the best tires to buy. We all need to be informed from places like tejas. Who knows we may have some new new owners or for that matter maybe some of the seasoned owners that could use the info. Shane's post showed how much bad information is out there. I am not as rich as Woody. I do not have 10k laying around a repower. I did a may consider and figure out to put a series 60. From talking to Rand and looking the specs. The 60 is a little bit longer. I know you can make any thing fit with a cutting torch and welder.

Hugh I believe one of the biggest problems we have is that so few Bluebird owners ever read the documentation that is available for their coaches. They rely on asking questions on the forums and then attempting to ferret out the answer from 20-30 answers or more from multiple forums. Not a day goes by that I do not see the same exact question on various BB forums with widely varying answers. Its a wonder that any of us ever arrive at an answer that does the coach no harm.

The question of motor oils for the Detroit Diesel 6V/8V/92 series 2 stroke engines has been going on for a long time on these forums. There are very few oils that are recommended by Detroit Diesel for these engines. From their publication "Detroit Diesel lubricating oil,fuel and filters " it gives the specifications of oils suitable for these engines. I highly recommend everyone with a Detroit Diesel download this publication and keep it handy to refer to http://tinyurl.com/7m72dt

If you read the Tejascoach article I noted you can see the damage that you may do to your engine by using an oil that is not recommended. With replacement engines so expensive can any of us afford to be lax in taking care of our engines? New owners of BB should be guided to this recommended information before they can do damage to their coaches. Then if they continue to maintain their coaches in violation of these recommendations they have no one to blame but themselves when their engines go BOOM.

I aint rich hugh----just hard headed

now what oil do i use now????????

I know i will use the rotella t as i do in my 2001ford and my 2008jd tractor...but...........

What do you all think?

[warbucks13477]

First of all you do not have a Detroit 6V/8V92 Woody so this discussion does not pertain to you. But if I had a Cummins or a Cat 3208 then I would definetly be using Mobil Delvac Super 1300 motor oil in my engine. This isnt about being hard headed Woody its being smart. This is the oil that when compared to Amsoil synthetic oils came out second even above Mobil 1

And its available in Advance auto, NAPA, Walmart, Pep boys etc.
