Your a good helpful lad with tons of experience regarding repairing volvoś , but are a bit too submissive regarding volvo regulations and always chanting on the knees for their altar
Now were i come from ,regulations are good but good critical thinking is better when circumstances are changing


Im not a fan of those wateroils, only if they are used in artic conditions with a lot of start and stops .
Volvo (and others) are using these wateroils to squeeze out every bit of emissions that they can get to meet regulations on paper , and thats also money if they can sell their cars that way
Engines are wearing quicker with those oils than thicker synthetic ones ,oil analysis proves this .
The unwary car customer wont notice since "servicelife" means a few years of warranty not 20 years of usage outside warranty .
Most people who come here on this forum have old cars outside warranty , and are better suited with good practicle advise when the engine starts using oil outside warranty

Now the pre dpf d5ś where using 5w40 synthetic how come?
Why did they change that into 0w30 with dpf? (same cilinders same pistons same clearences)
Odd aint it? Ill tel you why: emissions and dpf ashloading that doesnt mean that 0w30 oil is better for the outside warranty 10 year old car customer .
If you add in the extra fueldillution with dpf operation in the already thin 0w30 than im not suprised that a lot of those d5ś have valvelifter problems that pre dpf d5ś with undilluted 5w40 dont have
You do the math
Also the scam that only castrol can be used is moblike other brands that meet good wear and ash specs are just as good (or better)

The ashdifferences in 5w40 and 0w30 arent that much anyway and if you factor in less evaporation with 5w40 and less blowby then fewer oil will be burned that produces ash anyway.
Now even if the dpf gets plugged eventually (outside warranty remember ) than your holy volvo tries to sell their customers new dpfś for big money instead of recycle them by cleaning them with burning and reverse pressurized air like the trucking industry does

Thats odd behaviour for a company who claims to be sustainible to throw good dpfś away to sell their customers new ones

The crap ive withnessed first and secondhand with those companies are outragious
Axelping for instance : easily fixed with a xc90 bolt with a rubber ring, volvo refuses it because the bolt is only for xc90! yeah it fits perfect on other models , they are trying not working crap with locktite and disassemble axles for big money

The list goes on and on and on and not only with volvo also other brands operate this way
Fixing very old cars with bills more than their value , while cheaper commonsense options where availible, but dependend non technical customers are talked into it and gotten to the cleaners
Those talking suits with toothpaste smiles on their granit floors disgust me
