This is a newish youtube channel and it tries to explain lubrication. The guy is an actual lubrication engineer, and chemist. It's a good channel in case you want to learn about lubrication at a higher level than the general midwittery at BITOG.

Thx.

 

I feel like half of the S2KI forum are members of the BITOG forum

 

Do they have suggestions on a favourite oil ? That looks like a great site but the info looks like it would take a while to go through it all. I will go through it as I have time, thanks for posting.

I just bought a 25 year old Honda that does not burn a drop of oil and the engine runs like it is practically brand new. It was just run on basic over the counter oil most of it's life. It basically runs as good as any Honda I've owned that I ran on high end synthetic oils in the past. I was a regular visitor on BITOG, but at the end of the day you just end up more confused than anything, information overload and an overwhelming number of opposing opinions on any subject.

After all of my years searching for the fountain of youth in motor oils I've come to the conclusion that any quality oil of proper spec used with a quality filter and changed regularly is going to work really well in Hondas that many of us own. If I was tracking/racing a car I would think differently about higher end oils, but for daily driver street use any good OTC oil will serve well enough.

 

I noticed, over decades, that the cars I had that were serviced with dino oil (they all get changed at 3-4K miles) wind up with a dark brown varnish especially under the valve cover. Cars with synthetic look brand new.

 

I agree, you can tell when an engine was run on conventional oil by the darkish staining, I've had some older engines cleaned up by running synthetic oil after being lightly varnished, synthetic oil has good cleaning properties. . My 96 Honda has some of that staining, but the engines still run great and they often do not burn oil, even though varnish can cause oil control rings to freeze up. . Your S2000 motor is super clean for sure, that looks great.
