Unfortunately, the person I bought my 95 854T from did not take care of the car like she was supposed to. Not only did she ding and scratch the hell out of the paint (cost mucho dolores to repairo) I'm almost positive she probably never took it for oil changes/tune ups, etc at the correct intervals. The only two saving graces where that one, she had a very respected private volvo mechanic who took personal care of the car for the duration of her ownership - and two, I drove the car fairly regularly for two years without any major problems before I bought it.
All of this aside, last summer I dropped her off at the airport and took the car for one of my regular two week long "babysitting" sessions. Just like I always did when getting the car back home, the very first thing I did was check fluid levels, tire pressure, etc etc... well - to my horror - pulled out the dipstick to check engine oil level/color and saw nothing but what I ended up describing as oatmeal on the end of the stick... (
Took it to dealer IMMEDIATELY. Well, you can imagine my relief when the tech let me know that they changed the oil and ran the usual supects of tests and the car was fine. He said that it simply hadn't been checked and topped off since the previous oil change (eeegads!!! don't try to tell me that's okay!) But anyway, the motor really was fine. The funny part is that aside from the looks of the dipstick, there was nothing out of the ordinary going on in that engine (prior to having to hit the lube emergency room) that would have indicated to me that something was seriously wrong (for example; THERE IS NO OIL IN THE FU#$ING ENGINE!!)
I've kept a close eye on all service intervals for the car since and it is running just fine. Still a whiplash-fast kind of quick from the engine, smooth idle, no alarming DTCs, noises, smoke, etc... On one hand, I ask whether or not I should still be alarmed of the sludge once found in the engine even if it still runs very smooth at 140+k miles? However, this little incident just fortified my respect for how tough these machines are really built. I've heard enough people say that Volvo engines seem to be able to handle more abuse than those of their peers in the industry, but it actually really amazed me that despite the situation - one of which would have landed other marque owners to hit the new engine store or much worse - this swede had no idea and just kept on trucking.. er volvoing...
