13K on the odo and I am still very confident that I made a very good decision! Even with temps in the teens and 20s, and winter blend fuel, I still managed 21.1 mpg back and forth to work.

I'M AMAZING? You completely ignored the part where his data was corroborated by the NASCAR results? His reasoning for the pressure tests was explained, which was to avoid waiting 100k miles to find out you chose the wrong oil. Pitiful. I STILL have no proof from you he is as wrong as you say...

Actually, he DOES say why the "increased pressures that a normal engine will never see" are important in seeing how well a particular oil protects. (So, how do you conclude he is wrong?) He ALSO has a section where a NASCAR team asked for his opinion on the oils they were using, and, the oils...

This ONE GUY is the only one who does tests like this. His pedigree speaks for itself. He actually DID do some tests on oils with 5k miles on them and also explained quite a bit of why he believes the tests he performs are quality tests that actually DO corroborate real world results of...

That is NOT what I was advocating. I clearly stated I gave that up after further research and consideration. Bob the engineer(as you call him) has clearly shown Empirical Data to prove what he is saying. If you want to get all up in your emotions and cling to the old standards, go for it. Was...

I do NOT disagree with the diesel engine approved point. I have conceded that in earlier statements. (Although I did argue that some of the detergent/additive packages in both gas and diesel oils are "similar", hence rated for use in both) Quotes from the blog: ...."Motor oil exists in “TWO”...

No. The author stated that the reason for the pressure testing is to test how the FILM protects, vs the "hydroscopic wedge" running in between the bearings and the journals. (Which per the author, regardless of weight has the same psi load in that capacity) It has mostly to do with formulation...

I just looked again further down in the testing data and found this: Diesel engines don't operate at the high rpm that gasoline engines do (although 4,000 rpm is pretty high for the ecoDiesel per se) so, I am worried about the pressure values (wear prevention ratings in psi) for really no good...

Okay, I see the GF-5 (gas) vs the CK-4 ratings (diesel) having to do with soot buildup (which increases viscosity and shearing) and longevity of DPF and emissions devices. I am seeing differences in the Boron content, but the Calcium is similar, Zinc is lower but we supposedly don't care, so...

“NEW” 15W40 Shell Rotella T Diesel Oil API CJ-4, CI-4 Plus, CH-4, CF-4, CF/SM, conventional (lab tested 2012) Silicon = 3 ppm (anti-foaming agent in new oil, but in used oil, certain gasket materials and dirt can also add to this number) Boron = 29 ppm (detergent/dispersant, anti-deposit...

VERY interesting reading, thank you for that!! I don't even remember seeing Rotella T6 in the wear ratings chart. My reading for wear resistance shows me that 0w20 Quaker State Ultimate Durability has more wear protection than just about any other oil out there (unless you can find a supply of...

Awwwwwww crap.

What I thought. Like E85 for gassers. Just cheaper.

Really wondering how it affects mileage.

They are supposedly rated for B20 Biodiesel too. Anyone have any experience running this??

Yep, daily driver here too. Why I got the 1500 since I don't expect to tow over 9200 lbs. I am just tickled silly about mine!

Tell them to loan you an ecoDiesel till your new one comes in!

How much time do you have? Personally, I do NOT like waiting. However: I know a guy who ordered a Boss 429 Mustang in 1970 and got tired of waiting so he pulled his order. The vehicle came in 2 weeks later. Needless to say, the ecoDiesel will probably not appreciate as much as the Boss 429...

I have heard this before also. My Son also swears by it. Also heard it several years on the original Top Gear. They were testing a diesel sedan and the "presenter" said he did much better with foot driving. I use cruise control because I don't want to get pulled over for excessive speed. I have...

No, but I found out if you over fill it, it will spill out of the fender in front of the wheel well housing!!!! OOPS!!
