Mobil efficient vs BP...does this make any sense?

[Whipped500]

Just an observation but I tried a tank of Mobil efficient and I swear I'm regening less! BUT it also seems like it doesn't have as much power. It seems like it doesn't shift out to a different gear to get RPMs down and MPG up.

 

I have always used BP from the same station but decided to try this Mobil efficient this time. I'm happy with less regens but MPG seems to be down by 1 and the somewhat lower power.

 

Devils advocate...I just may have not noticed the regens and MPG could be down because it's idling longer in the morning because it's getting colder here now.

 

I have to fill up soon but haven't decided if I'm going to do another Mobil or back to BP...either way, the next tank will have opti-lube XPD in it. All previous tanks were just diesel.

Once upon a time I use to know the answer to this.....before Micky D's started making diesel fuel.

I know what the crude cut is but what they are mixing it with

I don't have access to BP/Amoco in this market but like Grumpy was in the lubes and fuels biz for a lifetime.  The additives of XOM diesel efficient are exceptional.  I would agree there is less regen from that cleaning effect because of less soot/contaminates being detected in combustion process and out tailpipe. 

 

They did NOT increase cetane in XOM diesel efficient and in IL its being cut with #1 diesel so there's your MPG decrease. 

 

CountryMark/CENEX/CO-OP are highly recommended in your market with great additives and fresh feedstock from the CountryMark refineries. 

 

I have a neighbors 2001 F250 Super Duty 7.3L Turbo V8 4X4  for the winter up here and CENEX Roadmaster XL has improved smoke, starting, noise on that HDIU IH clatterbox with NO other fuel additives. It has 305,000 miles on it and owner was using Power Service and it was a waste of money based on my testing and use of this unit since October. Its not EGR'd or aftertreated but the changes are amazing with better from the pump/refinery fuel. 

 

 

 

BP may be higher cetane and using a standard add pack with mostly #2 diesel.

When I had my trailblazer ss and was on the enthusiast sites. There was lots of conversations about different brands and who was the best. At that time I did lots of sales type stuff equipment training. My most interstate driving. The seat of the pants was the same on whatever brand. For obvious reasons that vehicle saw the most abuse. Fun times. My diesels saw truck stops. I figured high use better fuel. My current gassers and higher mileage whatever is cheaper and higher usage.

Stan, you bring up a good point about the fuels market. In general its true refineries make a regional fuel and then the only delta is the additives racked in.   There are synthetic and advanced diesel fuels that are refined to exceptional quality but good luck getting them and you'll pay. 

The only thing for normal people is try to use  best out of refinery product with an advanced add pack.  Of course Exxon Mobil use that in reverse, use the lowest cost refined base and add a ball busting add pack from infineum.  

 

The old CO-OP fuels I mentioned above are usually refined close to the market and do a few extra steps, in Country Marks case they are actually using feedstock from Illinois, Indiana, Ohio so its fresh and really well done. Then they add very good adds at appropriate doses and actually mix it in so its not top treated. 

 

Top treating is ineffective for most diesel fuels and gasolines for sure.

Mainly for conversion. Not to be a wise as$. The regen can detect type of fuel and cleanliness. And cycle accordingly. Rather than RPM, miles, idle time etc. for it’s processes. But when it comes to oil changes the technology isn’t advanced enough to trust the oil monitor? I’m not looking to slight anyone, I’m confused. My CRV at 8K miles is at 40 percent. It was at 20 percent last time and got changed. More Hwy miles this time.

I use to have trouble sometimes getting good fuel. I’d carry as much as I could. We eventually added extra filters. Fast I believe, that was my brothers department. We did use fuel additives though by the drum full. Even venture into bio fuel. We processed our own. Now they are back to gas even the service trucks.

[Whipped500]

I know I should try both with my additive to see the outcome but....

 

Would going with BP and the opti-lube possibly bring back the power/MPG and lower emissions/regens...hypothetically?

 

Would running the Mobil be a wise choice in warmer months when they aren't cutting the fuel for cold weather in IL/WI?

 

What confused me about everything is that with less regens I figured better mileage. I also figured the cetane was higher to make it burn cleaner for less regens...but like I said, it seems lacking a little power. 

 

At this point I almost feel the less regens is better than the mile or two MPG because i use this truck for work which is a lot of short distance service calls.

[customboss]

Dave, if its regen'ing less it's probably burning fuel cleaner.   All the fuel is going to have at least flow improver for cold weather.

 

Most may be mandated by IL and WI to add in #1 for cold too.  I would agree fewer regen = better MPG. 

 

Higher cetane was not part of XOM's theory. They can add lower cost additives from the additive company they co own with Shell and not spend money bumping up expensive cetane rating improving adds. 

 

Confirm which diesel we are talking about the 6.6L  or 3.0L engine? 

 

Let us know how your experimenting goes!

This is in my LM2, my LML doesn't get driven in the winter 

[customboss]

A friend has a 2022 LM2 in a GMC AT4 here and we compared the CENEX Roadmaster XL to all the other fuels available here, Conoco/Phillips66, Loves, and he's a Texan so he's using whatever available there and the Cenex kills on performance and MPG. He's not regening much so far. No fuel additives ever. 

 

He's in Dallas area now and trying diesel efficient but hasn't said anything about it yet. 

 

He's supposed to pull a oil sample soon and that will tell me alot. 

[customboss]

I tested this a few years ago and if you want cetane this is the most miscible I found top treated. That said you want something refined in or racked in.  I have no idea if this is compatible with the LM2 design but for the people who used it that were customers their regens dropped and MPG went up with cheap ass West Texas #2 diesel from Big Spring.  Trust me they put nothing in that blend!  LOL

I have 16,000 or so miles on my LM2.

 

I installed and idash (for ****** and giggles) and have logged every regen for the last 11 months / 13,000 miles.

Some longer trips during the warm weather, but most is daily driver / local trip miles. 

 

Despite what I expected to see, the 550 - 650 mile intervals occurred when towing. (exhaust temperature is quite a bit higher towing, but not as hot as regen)

 

Except for some purchase at the far end of some of the summer trips, all fuel is from the same fuel depot/cardlock. 

 

Anyway, point of all this is that I'm not convinced a tank or two of different fuel will give an accurate indication of 'miles between regens'.

 

 

 

Remember --  except for a few fills, all fuel from same supplier, same location.

Can you add your fuel usage in some comparable value so we see how MPG or fuel consumption relates to your data?

What is confusing me is I seem to regen about every other day (while using the BP), but since using the Mobil, it's been 2-3 times the whole tank.  

 

It seems I regen a lot more...but my driving is also short, local trips so I attributed it to that.
