I also bit the bullet and went to Costco this morning.....Paid $4.49 for regular. It's painful pulling the new 5th wheel at 7-9 mpg.

Within 3 weeks time gas prices here went from 4.29 to 5.99 no kidding. Where will it stop?
story here, now most of cali is rural, but if you live in a population center such as I do in the bay area, the numbers are far worse. it is indeed up nearly 2 bucks in 3 wee
SOOOOOO ...I also bit the bullet and went to Costco this morning.....Paid $4.49 for regular. It's painful pulling the new 5th wheel at 7-9 mpg.
Diesel.I'm not sure if Rotella is for Petrol or Diesel engines. I'm guessing it is for Diesel. The manual states to use Pennzoil or Shell Helix. So if you are going with a Shell branded product, I would get Shell Helix Ultra 5W30 or 5W40.
However I would prefer using something like Redline.
The last time I looked at Rotella T-6 5w40 it was still API rated SM for gas engines, until 2010 I used it in all my Mopar gas engines that used 5w oil... Here is Shells information on the newer 5w30 T-6: Shell ROTELLA® T6 Multi-Vehicle 5W-30 Full Syntheticis uniquely suited for mixed fleets which run bothdiesel and gasoline vehicles as it meets both API CK-4and API SN performance standards.I'm not sure if Rotella is for Petrol or Diesel engines.

Say someone wants to find a good oil for his Hemi.
Redline sometimes an option, depending on availability. Now there's not a lot of choice in terms of substitutes because nothing has the additives like Redline and HPL is really not available at all. So, looking through an oil's VOA, how does someone determine that this particular oil will be good for the HEMI? What are the additives that one should look for and what are the minimum requirements?
After getting a somewhat older polaris (04) atv and looking online since polaris recommends all sorts of unicorn oils throughout their machines, a lot of guys run rotella t6 5w40 for diesels in them. I've been running it for the past 6 years now in mine and also run it in my swisher pull behind mower.I use that stuff in my diesel. I believe its CK-4. Are you sure you should put it in a gasoline engine?
Basically same price here in Central TX for 91OK - bit the bullet and went to Costco this morning - got there before 10 AM so it was only half jammed with confused old ladies.
$3.599 for Top Tier Premium (91 octane) with mandatory 10% ethanol via MN State Bribe, er, Law.
I concur. It is really good. I've run Mobil 1 FS 0w40. The one thing that I didn't like about it was that after the oil change, the engine would tick for 2 - 3 seconds and then it would be fine.Can you get Mobil 1 fs 0w-40? That would be my third choice after the two you listed based strictly on expert opinions here and bitog, and notably David from HPL who has commented that that M1 0w-40 oil performs very well especially given the price; I forget his exact words but something along the lines of "almost too good for the price".

True enough, but more related to sensitivity of the silly HEUI injectors and high pressure oil pump setup.Anyone can promulgate the narrative for their product.... Let me explain...
On a few occasions I had Ford Powerstroke owners (7.3L) come to me with a "slipping transmission/low performance" complaint. In all instances, they had changed their own oil and installed 5W30 Rotella in these engines.
Doing diligence, I scanned the computer, specifically looking ac ICP parameters. In all cases, the readings were all over the place and at WOT, they were very low/ unstable.
In one case, the owner just KNEW his transmission was at fault and was prepared to spend multi thousands of dollars for a new trans.
I called the man and asked if he had changed his oil and filter (evidenced by a new filter and relatively clean oil) to which he answered to the affirmative.
Being that the oil seemed mighty thin, I asked what weight he'd used and he said that he'd used 5W30 Rotella.
I informed him that the requirement was for 15W40, to which he dug in his heels and rebutted my statement.
He was totally convinced that the trans was slipping, and stated so. I responded that I'd like to change the oil to the 15W40, and offered that, if that didn't fix it, that he got a free oil and filter change, to which he agreed.
It fixed not only that truck but several others beyond.
I could have been a crook and put a reman trans in the truck and quietly changed the oil, and he would have happily paid for a very expensive repair that was totally unnecessary. Gee, I wonder how often THAT happens?!
This goes back to following manufacturers' mandates for certain specified maintenance requirements for their vehicles. Ya think, maybe, their billion dollar R&D departments might trump aftermarket "wisdom"???
Food for thought!

Thats the key word. The "lifetime" fluids are bs and so is spec'ing a lighter oil 0w20 to appease the epa. The bean counters (to save money) over rule the engineers in a lot of cases.certain
The bean counters often gain the upper hand because they pay the engineer's salaries.Thats the key word. The "lifetime" fluids are bs and so is spec'ing a lighter oil 0w20 to appease the epa. The bean counters (to save money) over rule the engineers in a lot of cases.

I learned that the hard way.Guess it's not quite as simple as "just do what FCA says".

Question for the oil guru's, if you add 5w20 to a 5w30 it changes the viscosity yes? What about the winter rating? How can you add a thinner oil to a heavier oil and NOT change the winter rating? The cold pump for a 20 weight is different then the 30 weight to achieve the winter ratings. If you want to make the 5w30 redline better at cold piston slap would not 5w20 redline added to it do the same exact thing as changing it to a 0w30? Yes you could always opt for the 0w20 redline as it would add vii's that 0w30 also has, and 5w20 does not, but wouldn't making an oil thinner however you chose to do it effect the cold performance and would that not change the winter ratings? Until we find an answer for what redline did to their 0w30, isn't this the best choice? 0w30 redline was substantially better at avoiding cold piston slap?
You know as well as any of us it depends what vis the base oil is within the SAE vis grade bandwidth, as well as the type of base oil (which determines the viscosity index slope) and VII additive.Question for the oil guru's, if you add 5w20 to a 5w30 it changes the viscosity yes?
