diesel oil

[charliemccraney]

With the utmost respect to everyone, you asked people "RESPOND PLEASE ONLY IF YOU KNOW WHAT YOUR TALKING ABOUT PLEASE...." Who here really knows what they are talking about when it comes to oil, period? I don't, so this is not an opinion, just food for thought. A Reply like "I've used it for 100k miles and no problems" is not an expert opinion.

My friend who has seen issues with it does not indicate necessarily that the oil is bad, per se, simply that it shortens the life of an engine. Something that may normally go 200,000 miles will need a rebuild at 150,000, for example. It is true, that most people here will never put enough miles on their truck to see the effects in their lifetime and if you're in this boat, it probably doesn't matter what you use.

Again, with respect to everyone, I'm not trying to step on toes or insult anyone, I think you should contact local engine builders, mechanics, and such who can actually see what happens, if anything. They will know. Many of us here are only "nothing bad has happened, yet" type of folks and hardly experts.

several years ago i did this and was told there is no problem in older style engines. i was also told using 15w40 was better than using straight weight oils.
my own personal observation is that it holds up and stays cleaner longer in my engines.
i also plug in my 1500w block heater below 25F for at least 1 hour depending on how cold it is, colder i leave it plugged in a bit longer.

hell its prolly the same stuff in a different bottle lol!

if the engine blows it just gives me a reasone to build a bigger better one!!!

True... I have no education on petroleum .....I did stay at a Holiday Inn once
But i have put over 5000 hours on a combine engine ,hot dirty severe duty
5000 @ 50 mph = 250,000 miles
Still running good.... Let me put another couple thousand on , & I'll get back to you

I love BITOG Forums

From what I know and have read, diesel oil is fine for gas engines. Some even have the API certification for gas engines(SL, SM, SN). I have read that people that have gas engines with emissions stuff like catalytic converters are cautioned because the additive pack in the diesel/HDEO oil can prematurely wear out your CAT if your engine has any oil leak issues, causing you to burn oil.

I personally would run a deisel/HDEO oil in my slick with no worries, if only I had a slick...Lol

X2, I ran Royal Purple because it was free! I ran Mobil 1 because my warranty required a similar oil, and did not specifically accept RP at that time, plus RP was less available nationwide in those days. I previously ran Castrol GTX dino oil mostly because I had had excellent results using it in my bikes. Back in those days Valvoline had an oil called Turbo Four supposedly formulated for turbo engines. I was running fairly modified Buicks in those days. If you are familiar with Buick's little powerhouse V6 you are probably familiar with their sorry oiling system. After days of multiple 1/4 mile passes, my Valvoline oil pressure would be less than 10 psi per 1000 rpm. I switched back to Castrol and regained a less worrisome pressure across the board after heavy passes.
A good friend built a Mopar Turbo III engine, installed it in a Shelby Shadow!, and proceeded to scare the grin off the faces of such worthy opponents such as ZR1's and Vipers. He had an oil pump drive failure while driving home from work, and at first thought the gauge had failed. He proceeded about seven miles home and found the locked up pump, He drained the Mobil 1 and tore down the lower end, only to find no sign of damage. He and I both have run Mobil 1 since, although he also has access to Royal Purple at no cost. This astounding car was the subject of a multi-page article in Hemmings, BTW.
Would other oils have done as well, who knows. The people whose opinion I trust as far as lubricants have some sort of vested interests in one product or another. I'm not sure there is one superior oil for all applications, we use multiple brands and grades in rotating equipment in various facilities, and it often is NOT the lubricants sold by that company. Royal Purple industrial lubricants have remained the choice of many operations for critical equipment involving severe services, although several has ceased such usage.
I have used Motorcraft diesel oils in my own equipment with no complaints or oil-related failures; if I could buy it at the mentioned price, I would probably use it in much of my older street vehicles as well. I would hesitate to use it in a cat-equipped vehicle; the small amount of extra ZDDD probably would never cause a failure, but again, who knows?
I have little faith in supposed "experts", especially in these times of every "expert" having their own agenda; current alarming information and misinformation regarding lubricants and fuels have led me to disbelieve most of what I read or hear!
After reading the same comments from Joe as those to which Charlie referred, I intended to stay out of this discussion, but here I am; I don't have any professional knowledge of lubricant superiority or inferiority, I simply use what has worked for me, and avoid those which MAY have been a problem in my varied applications! I suspect careful maintenance and care may be more of a factor than the particular oil.

that is most likely closest to the truth.

Years ago, I asked an old mechanic friend of mine which oil was best to use in my ol' IH Cub Cadet with a cast-iron Kohler engine. I knew what the manual said, use straight 30W, but I also knew the manual was written well before synthetic oils were readily available to the public. So what did he tell me?

He said, "It doesn't really matter which oil you use, just as long as you USE OIL!"

Meaning, regardless if it's a straight weight or multi-weight or what brand it was -- just keep the oil level up where it should be and your engine will give you a long & good service life.

I'd wager WAY more engines have died from the LACK OF motor oil than from what brand/type of oil was used during its life.

I have worked on ONAN generators for years they were always using stright 30Wt. [ Same as what I always used in my old Ford trucks ], then at some point 10-12-15? years ago Shell rotella came about, the older Onans were now using ST 1540 and that's is what I've been running in all of my previous old Fords and now my '65 & '62, again

thanks for all the responses guys,

do you know where i can see the sl sn rateing on the diesel oil im useing? xo30qsd motorcraft?

Joey,
I don't see the API rating noted in the Motorcraft description here:
https://www.fcsdchemicalsandlubricants. ... otor%20Oil

It may be listed on your container. If so, compare what the container "API donut" says to this chart:
http://www.api.org/certifications/engin ... 120210.pdf

I suspect the reason why you were able to get a deal on it is because Motorcraft (see description above) recommends it for their older (pre-1995) diesel engines and is listed by API as 'obsolete' now.

If what you're getting is in quarts, too cool, dude!
If it's in a drum, I would transfer it into clean, plastic jugs (such as windshield washer jugs) and watch as you drain it out to make sure it hasn't been contaminated with rust, dirt, water, etc. from setting around for a while. If you let it sit quietly and drain off the top portion carefully, any of those type contaminants, if there are any, should stay at/on the bottom inch of oil.

[therealjoeshmoe]

YEAH ITS QUARTS AND WE STILL HAVE A STOCK PILE OF CASES OF THIS STUFF HERE AT WORK.

[ICEMAN6166]

i notice a lot of the oils are "obsolete" now but there only seems to be a couple that are listed as not acceptable for use for our trucks.

[therealjoeshmoe]

SO I PUT IT IN MY DAUGHTERS CHEVY TO TEST IT OUT... LOL BETTER TO BLOW A CHEVY UP THAN MY FORD... IF IT DONT HURT THE CHEVY IT SURE WONT HURT MY FORD....

Joey theres a little button to the left of your keyboard it says " CAPS LOCK " on it tap it once before you start typing again .

I believe it's a SD rated oil made by Conoco-Phillips. It used to sell as a premium oil, probably due to the OEM connection. I have seen it advertised for $1.00 a quart, so I suspect it is being closed out. i seriously doubt you would have any problems with it in a non-cat gas engine.
