"Popular diesel oils used in gasoline engines" Its a well known fact that Rotella is used by a lot of people in gasoline engines.

Just wanted others opinions on if they thought it was an advertisement also.

Working in the diesel engine industry and dealing with this, I can say that diesel oil will kinda be changing. Mostly, the current grade of oil, CJ-4, will be replaced with CK-4. These two are very similar except for better resistance to viscosity loss due to shear, aeration improvements, etc.There is an added category of low viscosity oil called FA-4, and if you put that in your engine on track, and maybe on the street...it's toast. This big change will take place the end of this year, or early next year depending on oil manufacturer. IOW, your oil has not been changed much because the standard has not been changed in a while, and the changes in the new oil appear to be small.

I think all any one of us actually cares about is if our precious Rotella t6 will be changing

Rotella T6 will almost certainly change to meet the new standard. Whether or not the new standard will impact the usefulness of T6 for off-label appellations like turbo Miatas I have no clue.

Sounds like ok changes. Better high-shear/high-temp properties. As long as rotella doesnt become the FA-4. Though I feel like that would **** a lot of people off.

Do an oil analysis when you change your oil. Blackstone doesn't lie.

My last change of T-6 on Red came back with the expected high levels of Zinc and Phosphorus.

Formulations will change due to evolving emissions requirements (oils are no longer formulated to protect from wear it seems) and adoption of catalytic converters on diesel engines. But, at least as of the last couple of months, T-6 still has plenty of the good stuff and was otherwise giving good wear metal rates on my track car. YMMV.

I think by and large the changes are good, better aeration, less viscosity loss, etc. Shell may make an FA-4 version of Rotella, but there needs to still be older versions of the oil for engines that were not designed to use FA-4. Most likely, only large fleets adopt FA-4, leaving a lot of needed oil for everything else.

It would be nice if T6 base oil properties improved. Its pretty shitty for use over 7krpms right now. I still run it in the stock miata and the wrx but the race motor isnt having any of that. 8500rpm in a BP beats the bag out of the bearings even when you use good oil, I'd have probably spun a bearing in that motor if I kept using t6.

If you search for rotella formula changes you'll get posts from all over the internet with various modded car people obsessing over label changes and rumors, going back many years. I think it is safe to say that the guys who make rotella T-6 are aware of the off-label uses. If they have googled their own brand even once, they're almost certainly aware of it.

Knowing this, I'm pretty confident that the makers of rotella t6 are not going to change the formula in a way that would harm the engines of their customers without some sort of major warning or label change. Bricking the engines of their customers (even the off-label, off-road users) would be a major PR disaster, undoing years of goodwill that they've built up.

In short, I'm not the slightest bit worried.

Word:

Petroleum Quality Institute of America

When the API spec updates to CK-4 at the end of this year, would be worth it to check again and then watch your oil analyses.

Current T6 API spec is CJ-4 and SM. SM is entirely appropriate for our cars (it's even the acronym for Spec Miata fer' chrissakes'), so I don't know why we would be considered an "off-label" use. ??

Sorry if this is off topic, but what viscosity/weight T6 are you guys running? I'm about to pick some up but i'm unsure of what weight I should go with. I got lifter tick pretty bad after the track this weekend and hope to clean out my HLAs as much as possible with this oil and hopefully reduce the lifter tick.

Yeah, the t6 only comes in one viscosity. There are other oils under the name shell rotella, but they are not the t6 oil.

Just subscribed for it on amazon. I get a gallon a month for $16 each. I run it in 4 cars and a motorcycle so I use a lot. I wish I could subscribe to the quarts too. But you can only get those at wallyworld
