The consensus is, us a high quality motor oil, change it more frequently than you need to. Wax on ever so eloquently about why you choose this oil or that oil and filter combo, the quality of your UOA's and so on. Then hope beyond hope you don't get T-boned by a person in a dump truck running a red light when your car has 100k on it and it waste all your efforts. So few of us keep our cars long enough to actually see the validation of the efforts put into all the consternation and wrangling of thought of this process. Most of us do it for the pure enjoyment of the process and conversation. I personally in my life have never had a oil related failure or component failure, being a 50 year old and a avid car enthusiast I have had large number of cars and motorcycles in my life.
U know I think getting T-boned is more a chance these days than any engine failures. Yet at 65 years, I been around all sorts of vehicles , had many , worked on and enjoyed all aspects of motor cars and even racing. Worked on my cars and family & friends. Still wish I could.
Most magazines I bought and still do are always about autos. In all that time I only know of two incidents in my life of any engine failure.
#1 One was so long ago, my Dad's 1967 (Ford 289) that was settled out as a defect and covered under warranty.
#2 The other was a used truck that failed on a buddy not long after his purchase in 1985. He determined it was clearly not maintaned when he broke into it. Both were actual crankshaft failures. Almost an unheard of failure even then in a regular duty vehicle. He was able to clean it up, rebuild (Ford 302) and got many miles of use after. I had the same exact engine in a used truck also, but was lucky and it ran great forever.
You have to be an auto enthusiast , get enjoyment out of automobiles etc... to focus , question, research and even obsess as SOME of us do here. I fully admit to Oil Change Delusion (among other quirks as I face getting older).
It is a gift to find a site so full of so many individuals with similar likes and interests as is found here BITOG, to learn from and share with and yank each other's chains
now and then. Guess its all part of ownership and
at the $cost$ of many vehicles today we best hope there is enjoyment there as well.
Happy New Years and hope it is a better / peace filled one for us all. Happy motoring too.
