thanks Kane for the informative web page. link here
That's pretty impressive. I can see marketing Slick to the standard American or Japanese oil eating end of life cycle engine owner but not good for an already well functioning engine, esp. a totally non-oil consuming engine like mine (even if 16 years old!!)
My engine in 3000 miles didn't use a drop of oil. And yet I was suckered to buy a 4 qt package with qt. of Slick 50 because the price of synthetic oil was So High and the same additives seemed to be in Slick as in the synthetics. I shoulda just let the mechanic put his 4 qts of generic oil in. Btw, It's unique, perhaps, that Volvos have a perfectly 4 qt. fill at least in my case. 4 qts in and it lines up perfectly on the dip stick at full mark. I remember my Toyota was either 3 and a half or 4 and a half .. and if someone mechanic put the whole last quart in it was likely the seals would blow out and oil consumption would increase. That happened towards the end of it's life... the engine is still fine but used about a quarter of quart per thousand miles..not bad, but nothing like this Volvo which never moves from it's Full mark.
I suspect Slick maybe jazzing up my engine a little with clogging of micro gaps in rings perhaps ... thus why people love the stuff... In reading the article it seems that Slick and it's "teflon" additives isn't all bad, but likely to increase oxidization (rust).... which here in the northeast is the main killer of cars. Something I want to avoid. Although most Volvos (and Toyotas) here die of external decay, not engine destruction. Which is a real battle against rust of the frame and body.
I think I'll redo the oil when I go back to the mechanic's and have him change my car into it's new snow tires. It'll give him a chuckle, only cost about 30 bucks and we'll all feel better. I don't think this'll give my car major consequences and if I change the oil soon it'll help flush out the system better than it's been in awhile. I am now suspicious of synthethic oils too though as they market teflon in their oil too I've heard. Perhaps Paul can weigh in on that detail. His oil probably doesn't and the Mechanic didn't say anthing wrong with synthetic oils .. just that they might not be worth it for older cars and that older cars should at least be checked up on every 3000 miles anyway so having an oil change then benefits the car in more ways than just oiling it. He gave a demonstration of all the things he checks (radiator, battery, fan belts and I was impressed at what a deal 30 bucks is when going to a trusted mechanic....
The reason I am not psyched about changing my own oil: no cost benefits. (oil and filter of good quality costs almost the costs of having the mechanic do it if the time is included, and costs of discarding the used oil is included...) the only benefit is that I can do it whenever without leaving a car at a shop or going to a quicklub place where they'd with low wage employees like in other cars (like the Toyota) overfill the engine with oil.
