Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Any words for or against Lucas oil additive? I've always run Rotella 40 WT but can't find it in Walmart anymore. An additive seems like a good move 'cos I'm running in summer heat.

Lucas fuel additive?

Dogma is not much of an improvement over using ATF as far as adding lubricity to the fuel. Search, there's many testing claims regarding additives.

I ran straight weight 30w Castrol in a old 71 VW van I had way back when. It definitely ran better on straight 30w than 10w-30w, I had all the gauges on it oil pressure, temp, cylinder head. I put over 100,000 on that engine.


I haven't tried it in the CAT but have considered it. I don't see much trouble with oil consumption so it ain't broke, you should be checking your oil anyway.



STP is so thick I would think it raises the viscosity but with all the oil in the CAT it may not. STP used to have better stuff in it, ZINC I think was one but I'm not sure if any of the good old stuff is still in it anymore. Oils have improved and the EPA and other agencies have restricted use of a lot of stuff.


There a good report on diesel fuel additives on the web somewhere you can also search oil additives. I think Bob the oil guy is a web site.

When I bought my SP, I was using Rotella. Used a quart about every 250 miles. I changed to Delo 400 and used a quart about every 500 miles. I went to Cat oil specifically for the 3208 and older engines according to Cat, and it will now go about 1500 miles under normal driving, about 750 miles of mountain driving. I'm no expert at oil, but the Cat oil seems to works best for me.

One comment. No wish to start a flame war.

I did use Delo 400 LE API rated CJ-4/SM in my C8.3 Cummins for years. However, I stopped using it when the API changed to CK-4/SN. The old CJ rated oil had about 1200 ppm phosphorous and zinc. The new CK rated oil with the red cap on the jug is rated at about 750 ppm phosphorous and zinc. I prefer more phosphorous and zinc in my flat tappet Cummins.

Bottom line is: your engine, your oil, your money, your choice.

My saga with Delo: Back in the Yahoo days was a old boy named Tom Warner, he was a real serious type of guy who did a lot of amazing things to his PT. Tom was all impressed with Delo for some reason, can't remember why he was so high on the stuff, but I responded to his input by buying a drum for the shop. 15/40 Delo diesel engine oil. Changed the 3208 Toter home engine over to the stuff and immediately took a short road trip with a 40' fiver in tow, 200 miles round trip, no mountains or hard use. sucked up two quarts. DA*N I hate when that happens, called Dupree, he told me the straight weight and STP directions, rattled my memory, what I ran in the rat motors in the past. Anyhow, drained the pan, left the filters alone, filled with diesel tractor oil from Fleetfarm and STP, took the fiver out to Idaho and left it. Made it back to WI was down Qt. and a half. That's my experience.

Which CAT oil are you using, can you post the part number ?
Also what’s the viscosity?
I looked into CAT oil a bit and saw they’ve been using Mobil to blend they’re oil, so it may be the same as Delvac.

You're not burning it, you're blowing it out. The 300HP likes it just about 1/4" below the full mark. Try it and you may see a difference. That is what Pape suggested to me and it worked for me. Your oil stick is not standard to the 3208 so your reading may not be accurate.
