Engine oil

We have been using rotella in all our engines for the past 20 years or so.Question is there any better that rotella some say kendall?

Mike M · Feb 21, 2017

So have you had any engine failures ? If not then why change ?

Jerry Coulter · Feb 21, 2017

I was using Rotella 15-40 in my 1993 Chevy 6.5T. It threw a rod so I won't use it any more.

David G · Feb 21, 2017

I use Delvac, just because it is a little cheaper.

Jerry Coulter.....May I ask how many miles on the Engine when the Rod bearing failed?

Standard or Auto?

Thanks

Bob...

tests on Bob's the oil guy website show Rotella being in the bottom tiers of 15W-40 oils tested. Even their synthetic blends don't fair as well as some conventional Dino oils. Valvoline Premium Blue tested at the top of the pile. I have oil lab tested evertime I change it in my 2006 Dodge 2500 with Cummins. Change oil at 6000 mile intervals. Napa's house brand gives the best results for me, and is made by Valvoline for Napa.

Personal experience with any product is usually the reason you and I are for or against a specific brand I think. It's like Ford, Chev, or
Dodge pickup trucks, I doubt any of them are really any better or more dependable than the others. All kinds of people have good success
with every brand of most products, others have bad experiences. Assuming all oils meet the current SAE standard (or the standard when the
engine was manufactured), I can't really see how it is possible that one could be so much better or worse than another one. The fly in the
ointment (or the oil) is the product itself or plain ordinary luck (or lack of it), I doubt it's the oil.

I doubt the oil was to blame. I have been running Rotella T in my diesels (and some other units) since the late 70s. I have no complaints.

I had the forerunner to that a 6.2. Pretty low miles (less than 60,000) and the rear main was leaking really bad. Pulled it down to put a new rope seal in and the crank was already undersized from the factory and bearings were pretty scratched looking likely there from assembly time ! GM quality was really at it's lowest level back then ! I swore I'd never buy another GM product after all the things that truck had wrong wit hit from brand new.

I use Delvac also, it is well rated and inexpensive after the rebate.

stonerock · Feb 21, 2017

been running rotella for 30 years, no problems yet so I;am not changing, run it in gas or diesel

I run oil from Lubrication Engineers in my
service truck. I've got several customers
I've turned on to their stuff to solve
issues they were having such as premature
turbo failures, and heating issues. The he
simple change in the oil made a huge
difference.

I'm no oil salesman, but I've personally
athe results if thousands of hours of use
if LEs oil and greases over the past 20
years, in all types of equipment, and I
have no problem recommending their stuff to
anyone.

What many don't understand is the oil
itself isn't the problem as much as the
additive package used. In other words, the
oil can continue to do its job by being
there to provide Lubrication, but with the
additives gone it often allows fine wear
particles to stay suspended rather than
binding together to be filtered out. Thus
is often where the wear begins.

Thus is why some oils are only good for say
3000 miles, while LE has oil being run for
15000 miles plus and still testing good for
both the additives as well as contaminants.

Their stuff is usually more expensive than
the regular stuff like Rotella, etc, but it
saves you money in the end because five
times the life more than offsets the cost
difference.

I've run Rotella for years, but my oil guy says he thinks Kendall is better, now that they took the zinc out of the Rotella.
The machine shop I use sells CenPeCo - he says it's the best, but it's about 30% more than Rotella

Oil is oil,it all comes from the same place.No matter what brand you use someone has something they have been running for 30 year or so with no problem.It's like beer,no matter what brand it all does the same thing.

ericlb · Feb 21, 2017

ive been using rotella for decades in everything from single cylinder engines to semi trucks, never any problems with it, im going to stay with it, only thing i dont use it for is the wife's new jeep, it is supposed to use 0-20w, might as well use water

donjr · Feb 21, 2017

The engine or the oil???

Jerry Coulter · Feb 21, 2017

Hello Bob

I bought the truck with 104,500 miles not knowing anything about its prior servicing. I immediately began using Rotella 15-40 changing at 5,000 mile intervals. The rod threw at 173,500 miles. It mainly towed a 5th wheel camper for me and the previous owner. It had the 4L80 automatic tranny. Jerry

The problem with the 6.5 is the damper pulley and the belt piulley on the cranckshsft they need inspected and changed regularly or you'll break cranks and throw rods

Crazy Horse · Feb 22, 2017

So are you suggesting that Kendall regular (over-the-counter everyday oil) has the zinc additive? Hmmmm, I don't think so. Some specialty oils have it that are formulated for vintage engines, not rods etc, and specifically for those with deep pockets (VERY expensive).

Had CenPeCO years ago, salesman was a Pr,. Dad put him in his place and he never showed up again. Was saying the oil we had been using would not hold to the surfaces. Don't remember how Dad had some CenPeCo oil and was prepaired when he came again, he had a samole of each in a clear glass container and what we were using would hold to the container and the CenPeCo oil would run off like water, And I refuse to pay for the OVER PRICED SHELL ROTELLA. I will not pay for just a name the company has built up without any reason except pride.

I have heard that the Germans did use water in some of their aircraft towards the end of WW2, after they ran out of oil. Most of those flights were one way anyhow!

Jerry Coulter · Feb 23, 2017

The oil. I use Mobil Delvac now. I sold the truck to a guy who intended to replace the engine.

Jerry Coulter · Feb 23, 2017

My prior truck had the 6.2. I had no trouble with the engine itself, but a lot of problems with the injector pump, glow plugs and the 700R4 transmission. I loved driving it because it had full power steering rather than the weaker power assist that my 93 and now my 2002 has.
