Volvo had problems with rings and if not for a class action lawsuit I would not have known my car fell within the years of cars having a problem. After X amount of miles their cars would start consuming large amounts of oil. The lawsuit settlement was to expand the warranty to 8 years / 100,000 miles.
I learned of this problem in the summer of 2023 and had my oil changed in July 2023. We are retired and don't drive very much and in January I decided to check my oil level. I had 1400 miles on the car since the July 2023 oil change and the oil level was down to the first line of the dipstick, about a quart. I called the dealer and they said bring it in for an oil consumption test.
The oil consumption test is when they drain the oil, replace the oil, seal off dipstick and drain plug. Drive the car for about 1,000 miles, bring it back, they drain and weigh the oil. As recommended by Volvo forum members I was told to drive the car like I stole it, which I did and put 1,050 miles on the car. Took it back to the dealer and they drained the oil and weighed it. They said I only used 11 grams during those 1050 miles. Hm? Oddly this is what the forums said I would hear. I asked, so why did I use almost a quart in the 1400 miles. Answer - I don't know. My car has 52,000 miles on it, I have now reached the age limit for any warranty. I could not check my dipstick during the consumption test.
Now for a big no-no. I get home, look at the service report and dont' see any mention about oil, weight oil, brand, etc. I called and the service manager said, "oh, well because you only had 1,050 miles on the oil from the last change, we just dumped the oil we drained back into the car. What!?!?! Do you have a pristine drip pan, how do I know crap wasn't drained out the bottom of the sump and returned back to the top side. Who in their right minds would do such a thing?
I don't think I am wrong on this --- am I.
