Valvoline Premium Blue

here is the official recommendation from the red engine maker for the ISX. Some of those on that list, i would not use myself, have seen people have more wear on some than others

The stuff you are referring to ...
a person can use it, no problem. I think though that it has a slightly shorter lifespan than some other brands, may require oil replacement more often than some of the brands that have better separation and/or TBN loss preventatives.

Just because the engine maker endorses it, does not mean it is the beast thing out there. - That is somewhat mis-leading in my book.


Does not matter to me what the engine maker says (within a certain bounds) as much as application and use would dictate. Only way to know for sure if what you are doing is working well for you is to do some oil sampling. watch for iron levels vs. mileage on oil, and see what the results are after a few oil changes.


Personally, I don't think any of those oils are nearly as good as the pre-epa oils that allowed more zddp up around 1440 ppm (optimum) and the like. - A lot of these newer oils are recommended, zddp and other additives have been stripped out of them, not based as much on wear as they are based on emissions too any more, and this mis-leads the public.

(not implying this towards anyone, I just see this with some people, putting it here for reference on those people who might be like this )...
LASTLY: I HAVE NO IDEA WHY!!--- some People are so hell-bent on finding that perfect brand of oil, and do all kinds of looking on the internet and discussing to death, what brand, and spending all kinds of money and wasting time, focusing heavily on what brand of oil to use. etc.... -- yet they let the rest of the engine and its systems go to s$it around them.

BECAUSE!!!!-- I HAVE YET TO SEE AN ENGINE where the oil was replaced at the correct intervals recommended based on fuel mileage, etc... and a component fail because of the brand of oil they used (as long as it is any one of the top brands).. The engine never makes it that far, as it is always a non-lubricated component that inevitably causes the head to come off it and it get inframed. (valve seats or injector cups, etc. in head wears out, liner drops, etc.).

OF THE lubricated components that I do see fail,.. It is almost ALWAYS because the engine got sooted up and carbon packed real bad, cross-channels got clogged up, etc. ...

for one or more reasons of...

* They Did not change oil often enough, because they did not base it on fuel mileage, etc.. and tried to 'save money', stretching out their oil changes, engine always soot-packed.

* -- AND/OR they let the engine get packed up with carbon and soot because they did not keep after the emissions and egr system properly, do regular maint. and egr-tune-ups, etc. - they let sensors read incorrectly, let the dpf stay half-way clogged up all the time, making excess soot and back-pressure in the engine and turbo, then did nothing but complain against their own lack of knowledge. These types of people also will quite often complain that their oil pressure falls off after (usually) 10-15k miles, and think they can drive it around like this in a blind mirrage of idiocy instead of FIXING THE GODDAMN ENGINE PROBLEMS!

* AND/OR some moron went way overboard and used synthetic oil in their engine thinking it will cause less wear (victim of brainwashed marketing at its best), just because it has that magic word 'synthetic' (or 'expensive') on the side of the bottle ... but the fact is that the opposite always happens in the ISX. Trouble is that people believe that the additive package is somehow vastly superior on synthetic oils... I hate to break it to them,.. BUT IT IS ALMOST ALWAYS NOT! .. and because they spend 2 or 3 times more money like a fool on the oil alone... they then -- you guessed it ... only change their oil 20k+ or god forbid, even longer intervals, some of them use bypass filter and try to justify it falsely,.. and destroy their overhead cams repeatedly, then blame the ISX as having cam issues instead of looking in the mirror.

* AND/OR -- Some fool puts thinner oil in it thinking they can save a few tenths fuel mileage and everything wears faster as a result.


* AND ESPECIALLY-- If they do not adjust the valves often enough. THIS ALONE is another one right at the top of the list. The valves should be re-adjusted every 250k miles maximum, I don't care what the red engine maker says. if not, the rollers start riding the cam all the time and it eats itself to death.

* OR LASTLY--- THEY put in a bottle (sometimes 2) of that over-priced 110-grade $35+dollar a gallon way-over-priced oil in the white bottle that is market everywhere (PUKAS) THAT HAS ZERO ANTI-WEAR ADDITIVES IN IT and only serves to thin out your oils (alrady weak these days due to epa regulations) additive package by another 12% when they pour it in. - Raising viscosity on the ISX is actually helpful long term,.. but there are some far better products that can get it there.


that is my own experiences anyways.
