Sometimes when working on an older vehicle, it's just surprising to see how clean some engines are when looking through the fill cap or removing the valve cover or intake.
I'm sure there are some out there with stories to tell about an engine they've seen with high mileage. Please share what you've witnessed over the years.
I used to work at a dealership many years ago. There was one customer that used to bring his own oil which was conventional Shell Fire and Ice 10w-30 (I believe that was the predecessor to conventional Formula Shell) to use in his vehicle and the first thing I immediately observed when taking the oil fill cap off was that the engine looked like new.
I mean I’m talking about a vehicle that had many miles (over 140K) on it! I ended up changing the oil on this vehicle many times afterwards using the Shell oil that he brought. The engine was spotless when I first started doing the oil changes on it and it had many miles and it remained that way until I ended up leaving the dealership.
I actually spoke with the owner about how long he owned it (since new) and did he always use Shell and he said yes. That particular vehicle and the details around it just stuck with me long after leaving that dealer.
Conversely, the oil that the dealership used did not keep engines nearly as clean as that conventional Shell did. I’m speaking in terms of other customers that kept up with their maintenance routine as well as the Shell user did and their engines had noticeable varnish. Not sludge, but very noticeable varnish.
Anyway, what I’m getting at is please share your stories about engines that you’ve seen that were pretty much spotless after many, many miles of usage. Share the type of oil, viscosity and other details you consider to be important.
I’m curious to hear what others have to say.
