The idea is like a dpf cleanse, you get things hot enough to turn the carbon into ash and then it should scrape into the sump and hopefully get caught in the filter.

I suspect that he was referring to petrol engines, eh?

Maybe, but the principal is the same.

Repair will be a cost but it will add no resale value to the car. If, however, the car is in good condition in all other respects then the repair will add value in terms of what the car is worth to the owner.

Replacement depends upon what the replacement car is, how much it cost, what it will be worth to the owner, how much maintenance it will need, the cost of depreciation, what profit the seller made etc. A complex calculation.

For most brands the decision is probably a no-brainer, but Volvos are a bit different. I bought my first Volvo in 2011. It was a 1998 V70, i.e. 13 years old but a lovely car. That car is still on the road in 2022. You won't find many 1998 BMWs, Mercedes, Audis or Fords on the road, however.

You are totally right!

I need to think about my issue, because i really love the V60.

Many thanks!

Hello all,
One general question for all based in a suggestion that i got from a technician.

So first of all he suggested to check if there is no issues with the oil sensor, ok i totally agree, so fill with new oil, measure it, drive 2000 km and after this check the consumption, measuring the oil again.

But the most strange suggestion, was to replace the 0W20 to 5W30. This makes sense?

0/20 is thinner so more likely to go past the rings, 5/30 is thicker so less likely to burn through,

Is the tech a Volvo one or just a dependable knowledgeable usually independent wrench? I would love to say use the 5/30 especially if your location never gets icy cold like Sweden etc but the 0/20 might be essential not to clog the scraper rings up.

nonsense it is the incorrect oil . oil systems now are much more sophisticated than before with variable displacement pumps , piston cooling jets tighter bearing clearances , balance shaft housings spur gears etc.

Interesting vid, but as others have said it's seems to be the petrol engine they're referring to, though the VEA diesel issue may be similar.

What I think it does tell you though in my opinion is regular oil changes with the correct grade and quality of oil is likely key, I'm skeptical that running the engine at high RPM would clear that, the temperature of the piston skirt would never be hot enough to burn off carbon like that.

Me too originally but if you get the oil hot enough it should do some cleaning due to pressure and also carbon weakening as the scraper is a 3 piece ring that's not fixed together allowing movement to also crack solid crud to be dislodged, hot and cold extremes have good cleaning properties, an example is it you find chewing gum in your carpet to freeze it to remove it by causing it to become brittle.

It is the oil drain holes through the pistons behind the oil rings which can get crusty you can never get rid of it without dismantling . A modified piston was fitted half way through 2016
