Hi everyone
Just brought home this great White truck.When I first tried it I noticed the oil pressure was 30lbs cold on the addon oil pressure guage.Little low but after all it as a 1954 with 110000 heavy use miles.The owner told me he had carb problems and a lot of gas had dumped into the crankcase.I had just checked the oil and was amazed at how clean it was.I understood now why.
Got it home and drained the oil .Filled a 5 gal bucket.2 gal of gas I figure was in there.
I put Rotella T1 SAE 30 oil in it thinking it was non-detergent.Bad assumption!After having shown my truck driver of 60 years friend the container and having him say it should say non-detergent I kinda of panicked.However the truck ran better than ever,did not smoke at all and the oil pressure gauge showed 60lbs cold at idle and 30lbs after warmup at idle.

Now that the engine is absolutely cleaned out do I change it back to Wolfs Head SAE 30 non detergent or stick with the Rotella T1?The Rotella works great in my diesel trucks but although I have searched for hours I still don't know what White recommended on their truck but am pretty sure it must have been straight weight non detergent like my old F8 Fords used to run.

Please anyone who has an opinion reply!!!!

Thank you very much

I've always used 15w40 diesel rated oil in my '56 WC22PLT and '64 4200. Several years ago I pulled the oil pan on the '56 to check for sludge and it was completely clean. Oils are much better now than when these trucks were new. My White manual for my '56 shows 30 wt summer and 20 wt winter. I think a modern 15w40 will work fine.

There are a couple opinions about detergent/non detergent in old engines. Opinion/science about detergent oil is it suspends contaminants in the oil instead of allowing sludge buildup, but detergent does not scrub sludge and clog oil passages (which some people might warn about). I've used detergent oils in all my old engines, whether they were cleaned during repairs or woke up after sitting 40 years, and I've not had a problem. This was also the experience of people in an AACA article in the 1970s. So I'd say just leave the Rotella in there.

Congratulations on getting your White running, have fun!

Hi guys
Thanks for the quick replies.My friends in the club have said that the Rotella T4 15W/40 diesel rated oil is the only one they'll use in their GMC toro diesels because of the zinc contact of 1000 parts per million.This is also all that I've been using in my diesels for years.Nice to hear you've been using it in your White without problems Tony and you in your old trucks Bruce.Is that also the 250A 386ci flathead 6cyl engine in the 56 White?
Now I found a multiviscosity oil that has 2000 ppm of zinc available in 10w/40 20m/50 and straight SAE30.i haven't found out yet if it was rated for diesel engines but I do know it is a detergent oil.I have a question out to the manufacturer and am waiting for a response.Any information I get I will surely pass on.
You know after this gas in the oil experience I can't help but think that the gas didn't losen up the sludge and carbon but broke it down and lowered the viscosity to a point where all the junk just went down in the pan or into the oil filter.I'll be changing that.Now I don't know what would have happened if the oil pressure had been lower but i don't think I want to know.
Thanks
Rich

As said before, detergent or not just has t due with keeping stuff in suspension or allowing it to drop out. Detergent is best with full flow oil filters and non was used with engine that only had bypass filtering. Either way on an old engine it isn't a bad idea to clean the pan and pick up.
I run detergent in my old K's after cleaning the sump.

WOW!!!!!!!!!!!!!!
NICE TRUCK.That inspires me to restore mine completely rather then retain its used condition
I'll have to get some more pictures posted.I have them on the computer but have to find them which could take hours.
Thanks
Rich

White 250A engine is 386 cid, 145 HP, 328 ft.lbs of torque. Probably works 2200 to 2600 rpm, top rpm around 3000. Engine model number is on the drivers side on a machined flat spot on the side of the block.

Rear axle would be White designed/built if the White script is cast in the housing, or stamped with wider letters on a sheet metal cover welded around the pumpkin. Axle model is stamed on that rear casing. Ratio is stamped on the driveshaft pinion carrier.

Something I've never seen mentioned is the Series 3 diesel oils commonly used in the 1960's. They had a high level of detergents. I would imagine lots of gasoline trucks used those oils back then so not much sludge left in those old engines. I spend way too much time on old farm tractor forums and every guy that buys an old tractor "Just like Grandpa's" asks the Detergent or Non-Detergent oil question typically After they change the oil with non-detergent because an 80 year old operators manual said so. Most guys are running Rotella 15W-40 T1 in them, gas or diesel. I've done it myself for over 22 years since I got my diesel pickup. If you like, run Mobil Delvac 1300 in 15W-40, or Chevron Delo. They're ALL good oils, just depends on what you like, I chose Rotella because you can buy it anywhere. Might have to look a little harder for Delvac or Chevron Delo.

The oil available today is so much better than what was available even just 10 years ago. Biggest reason cars & truck engines last so long now is improved oils and air & oil filtering. Changing oil & filters a little sooner is better than changing it too late. SON put my 22 yr old diesel pickup back to Daily Driver status this summer. 22 years and 300,000 miles and it still runs like new thanks to oil/filter changes every 3000 miles. It's done it's share of towing and hauling too.
