6V92TA oil

May 10, 2017, 10:32:01 am

We've put about 2000 miles on our rebuilt engine, with half of that after the oil pressure sender was replaced at the 1000 mile oil change. I've noticed two things in that time. First, the oil still looks new. Prior to the overhaul, the oil would be black within a few hundred miles. Second, now that the oil pressure sender isn't leaking the Jeep is staying much cleaner and there are NO oil drips on the ground.

Questions: Delo 400 40 weight oil is the correct oil for this engine, is it not? The jugs say the oil is NOT for DD 2-cycle engines. I'm confused.
Second, I'm going to start doing oil analysis. I'm guessing that now is about the right time to send in a sample for a base. What company is the preferred one to use?

No, it's not the correct oil for the engine. It requires Delo 100 SAE40 or another low ash equivalent. Shell Rotella is on the edge ash wise and Delo 400 is quite a bit over. Buy it or order it at parts stores or Chevron bulk plant. Chevron has a bulletin out on the differences. Also, never a multi-grade oil. The shop should have known the difference if they had any 2-cycle experience.

Read this PDF, especially the last paragraph: Delo 400

I use Chevron Delo 100 40 wt.
I buy 6 gallons (1 pale and 1 gallon jug) from a local Chevron oil supplier. They always have it in stock.
Supplier locater: Marketer Locator | Chevron Lubricants
Mine uses about 5-1/2 gallons (maybe a little less) for a change which leaves a little extra to carry around in case I need to top off.

Thanks. This is what MOT put in when they did the oil change. Looks like I need another oil change.

I recently bought a case (3gals) of Delo 100-40-1 at O'reileys. They didn't have it on the shelf it but had it for me the next day. I had to explain that it was specifically for Detroit 2 cycles and had them look it up on their inventory system. $19.99/gal.

I've used Blackstone Laboratories twice for oil analysis and am happy with the reports. Blackstone Labs

That almost happened to me at FOT. I caught the tech wheeling up the clearly marked Delo 400 10-40. I stopped him and had to convince the service writer that Delo 100 40w was the only thing to put in he 2 cycles.

I'd call MOT they owe you a refund.

They sure do owe you an oil change. Hard to have confidence when they are not up to speed on the 2 cycle oil requirements. They have been making this engine's almost identical brother since 1938 so it's not something new.

Yes, 5.5 gallons does the trick. I usually order 7 gallons and have some left over. On our coast to coast and back trip in the fall, we used just under 3 quarts of Delo 100 #40. Not bad for about 6K miles. 7 gallons and filter usually costs right about $100 in gallon containers from the bulk plant. Our local timber operator sells parts and filters for 40% less than NAPA for the same NAPA gold filter.

While I like Delo 100, you are not going to hurt the engine with Shell Rotella T1 #40 as it's sulfated ash is a bit higher but still OK. It's about $5 gallon cheaper too.

There are very few RV's on the road running 2smokes. I can see how this mistake happened. Most younger mechanics will not run into 2smokes unless they work on vintage machines.

My good friend has 12v71 in his boat and he's been running synthetic for years. Thousands of hours and almost no wear. He also just had multiple injectors seize up (mechanical DD). It's getting hard to find injectors that don't fail out of the box for DD. I saw the light and made sure I bought an RV and boat with cummins

. I do have an old dumptruck with a 4-53N....I had a 6v92 DDEC metro bus for a few years too.

I used about the same amount after 6000 miles that I've put on my coach since 2012. Johnson Diesel here in Biloxi used Exxon XD-3 40 wt. when I changed it in 2013. The specs are close to Delo 100-40 wt. I didn't know how old the oil was and and needed to get a baseline. I was concerned when my first Blackstone report showed wear metals higher than average across the board and fuel dilution was 3.0%. They suspected a leaky injector. Injector tests with my Pro-Link looked good and I wasn't too worried.

I started using Howes diesel treatment with every fillup. After 2000 miles I did another analysis and the results showed much better wear and metals were improved in almost all cases. Fuel dilution had dropped from 3.0% to 0.5%... a nice improvement.

I was waiting for the light to change to turn onto hwy 90 today when I heard a Fire Truck coming through the intersection. It was Engine No. 13 with a DD6v92. He was pedal to the metal and haulin' a$$!

Jerry,

A 55 gallon barrel of your Exxon XD-3 #40 just sold at auction for $71.66. https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=34&acctid=8071 Angry that they didn't take my $20 offer!!! OK, I'm lying, I didn't see it until it was sold. Would be hard to use it up. Fun trying.

I have had a similar experience with FOT starting to use Delo 400. I also caught them and told Alton the Shop Manager who quickly educated the youngsters of 6V92 oil requirements. I don't think one oil change with Delo 400 will hurt the engine but my experience is that the engine will burn it up quickly.

I can also confirm that you need the part number at most Orielly stores. They don't stock Delo 100 and can't easily find it in their computer. Just give them 100-40-1 for the gallon containers.

By the way my TOW STROKE DON"T SMOKE.

Okay, I have a case of three gallons riding around in the back of the Jeep. I had O'Reilly's order it in for me while we were at Truman Lake last week. I wonder if I can take it back to another store and have them get the right stuff. Have to call them tomorrow. Would it make any difference if I put in the right oil as needed, or should I just add the 400 that I have and then change oil on schedule?

On the way up to Lincoln yesterday I passed a sign advertising big rig oil changes for a certain price and that included a free steak dinner. Too bad I didn't know then what I know now.

Called MOT Thursday, left a message, and got a call back shortly before we were going to leave for a funeral. I explained the situation to them and asked that they call me back yesterday. They did, and admitted that they put in the wrong oil. They said that the Delo 400 was okay until fairly recently, when Chevron changed the formula. They have agreed to refund the price of the oil change.

Recently like in a geological time scale. What a spin. It's been years since Chevron made the change. In aviation, not only are there first class parts and shop manuals but the manufacturer and the FAA have bulletins and AD notes when problems are found. RV owners pay about the same price coach vs airplane but just get kicked down the road for after sales care.

Detroit 2 cycle owners should be looking at the specs for the sulfated ash as a percent by weight. The requirement is 1% or less. Delo 100 is 0.8%. Exxon XD-3 is close and well under the 1%. Detroit 6V-92TAs have one camshaft for each cylinder bank. The camshaft operates the 4 exhaust valves (no intake valves) per cylinder plus they have a lobe for each injector. The injector requires higher pressure from the camshaft and pushrod compared to the valves and this is where part of the problem lies. The exhaust valves may see more carbon with the incorrect oil and the low sulfated ash oil reduce the deposits. Single grade synthetic should be great in a 2 cycle.

David, good for you for being persistant. Squeaky wheel does get the grease.

Also the low ash helps control carbon buildup which will cause premature cylinder liner scoring.
I try and keep enough extra in the bay to do a complete oil change on the road if needed. Not that I have time or money to be gone that long. But I am prepared!!

My local independent parts store (in MD.) carries Castrol and they ordered two 5 gal. buckets for a waterman who had a DD in his boat. Engine in the boat died and the waterman didn't need the oil. They set it out to sell it and I saw it. Been using it ever since.

How about the Castrol name on the buckets? Is it Tection or another name? I can't seem to find it. A photo of one of the buckets would get great.

"Single grade synthetic should be great in a 2 cycle. " Suggestions?

We made it to Riverton a day earlier than we planned due to weather, and we're here until 5 July, so I've got some time to find someplace to change the oil. Several people have suggested that I switch the Jeep to synthetic oil, and I'm thinking that maybe that would be a good idea for the Detroit. I should probably switch the generator over, too.
