you dont have to use dexos2so I have a question because I can see that some of you diesel guys are geeking out on oils... lol.... I purchased my ECO 2.0 in 2014, and other than the oil that came with it from the dealer I have not wasted my time and money going to the dealer to buy their DEXOS2 oil. I see the huge list of compatible oils and that's great.... but my question is this: I've been using either Rotella T6 or Mobile1 full syn for all of my 89,000 miles. I like Rotella because it resists the acidic buildup in the oil and I can always find it on amazon or Walmart on the cheap In the gallon jugs. I have not noticed any faults from this oil, and a steady long life between oil changes. I did notice that the Rotella T6 gave between 1-2 months longer between oil changes when compared to the GM DEXOS.... but maybe I just drove it gently during that period, I'm no willing to purchase DEXOS rom the dealer at their prices.
in your guys opinion or that of science..... what are the disadvantages of me running Rotella T6 /Mobile 1?
Like I said, I only used DEXOS2 from the dealership once in 89,000 miles. my oil from the factory lasted about 5 months according to the computer. using Rotella the computer pushes the oil life out about 6-7 months. but that's just the computer, its not doing an oil analysis and giving a breakdown on the oil. only based on the cars computer is it lasting 1-2 months longer. where would I go to get a oil sample analyzed? that would be interesting to do a side by side comparison.you dont have to use dexos2
you can use acea c3 compatible oils, they are plentiful
theyre low ash, specifically made for emissions systems....not using this type oil, youll clog your dpf sooner.
in what way did it give you 2 mos more life?
yeah the oil life monitor in the car is just an algorithm, theres no sensor or anything testing the oil quality, you can reset the OLM and not change the oil and the monitor wont notice.Like I said, I only used DEXOS2 from the dealership once in 89,000 miles. my oil from the factory lasted about 5 months according to the computer. using Rotella the computer pushes the oil life out about 6-7 months. but that's just the computer, its not doing an oil analysis and giving a breakdown on the oil. only based on the cars computer is it lasting 1-2 months longer. where would I go to get a oil sample analyzed? that would be interesting to do a side by side comparison.
also, how would your oil type end up clogging your DPF unless your turbo is passing oil into the exhaust? all my diesel experience is Military related, we do not use DPF,DEF, or any exhaust sensors so that aspect is new to me. sh**, we use low grade 15w-40 in our motors and they are all turbo
Yeah, it's going based on ambient temp, IAT, coolant temp, driving styles/routes/etc. It doesn't change due to different oil.yeah the oil life monitor in the car is just an algorithm, theres no sensor or anything testing the oil quality, you can reset the OLM and not change the oil and the monitor wont notice..
Even modern Rotella oil is typically going to be "emission system friendly" or have "emission system protection". And as others have pointed out, that just means low sulphated ash content in the oil to protect the DPF. If you have an old bottle of it laying around look for something about low emissions or emission protection.Like I said, I only used DEXOS2 from the dealership once in 89,000 miles. my oil from the factory lasted about 5 months according to the computer. using Rotella the computer pushes the oil life out about 6-7 months. but that's just the computer, its not doing an oil analysis and giving a breakdown on the oil. only based on the cars computer is it lasting 1-2 months longer. where would I go to get a oil sample analyzed? that would be interesting to do a side by side comparison.

Short answer...higher ash content can potentially plug the DPF to the point where an “Active Regen” will no longer clean the DPF. This results in a trip to the dealership for an expensive “Forced Regen”.another question...... whats the big deal if the DPF gets "clogged" or "dirty"... isn't that what the DEF and the cleaning cycle is for? does this "filter" wear out?

Yeah, that is a good point that I did consider. The 14/15 2.0L only list 0W-30 as a low temperature viscosity to use. The newer 17/18/19 1.6L list 0W-40 as a low temperature viscosity to use.I wonder if they will suggest that for the CTD. They seem to only suggest an xW-30.
The owner's manual says:
"Viscosity GradeSAE 5W-30 is the best viscositygrade for the vehicle.* Do not useother viscosity grade oils such asSAE 10W-30, 10W-40, or 20W-50.* Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below −29°C(−20°F), an SAE 0W-30 oil may beused. An oil of this viscosity gradewill provide easier cold starting forthe engine at extremely lowtemperatures."
Will be interesting to see!
Found this deal on a 2-pack of 5-gallon jugs:Can’t find 1-Gallon Pennzoil Platinum Euro-L Full Synthetic 5w30 Dexos 2 at Walmart.com anymore...What the heck???
Used to find it all the time for +/- $25...any leads on other sellers close to that price?
I recently purchased a 19 Cruze diesel and fully intend to use Mobil 1 ESP 0w40, exclusively. Owners manual recommends 0w40 for cooler climates, but this oil should actually be better for all climates -- cold or warm. Meets Dexos 2 specs.Yeah, that is a good point that I did consider. The 14/15 2.0L only list 0W-30 as a low temperature viscosity to use. The newer 17/18/19 1.6L list 0W-40 as a low temperature viscosity to use.
However, I looked at the Mobil 1 0W-40 ESP technical specs viscosity @100c. It's just high enough to be SAE 40 by a few 1/10ths. SAE30 is anything 12.5 or less. This M1 stuff is a 12.9.
Now, if it were just about a SAE 50 (16.3 to 21.9) then I wouldn't, but I think it's close enough to use as a substitute for 0W-30 because it's so close.
And considering GM says 5W-30 is a substitute in the Vette's (street use) I think they are basically acknowledging this as well.
I still haven't been able to find it for sale anywhere at a reasonable price. Know where it can be found B&M? I'm currently running 0-30 ESP that I got at Naper for $5/quart as my winter viscosity.I recently purchased a 19 Cruze diesel and fully intend to use Mobil 1 ESP 0w40, exclusively.
