I think it's pretty reasonable to want to know what's going on inside one's own engine. I guess you've missed all of Bror Jace's posts (they seem to be missing now) on oil and filters? And $18 isn't all that expensive compared to all the other stuff enthusiasts spend there money on.

 

5w is really only necessary when talking 0deg=20deg weather.

perhaps with a 5weight though you would get more efficiency, as i do notice mileage suffering heavily in cold starts, (0-35 deg f)

maybe its to do with Honda's eye for the mileage bottom line, and less worry about that 250k golden line we all look for on our odometer.

 

lets just say it was a unique perspective on engine maintenance that i had yet to hear of, and to be frank it would be something i would look into, if not for the utility side of it than for that of just morbid curiousity.

 

meaning its a commuters oil, or racing oil?

 

Like all oil, it works well if you play nice with your engine.

They have a seperate line of race oil.

 

my car is 11years old, that 5w shiit will run through it like water, just b/c it says 16thousand miles blah blah....doesnt mean shiit anymore, my car isnt new, my motor is running harder than it probably did the first year off the assem line, i take car of my motor, by doing it at 3K miles and so on.

 

Nah you and Fuji are both wrong - it came out looking like normal used oil, but pretty black. Viscosity measured 68 on their scale, normal for the oil I used was 62-65, so it was a little high but hardly tar.

If your oil was thin, you had a lot of unburned gas in it - this is bad, could be due to rings, need of a tuneup, or excessive idling.

Normally, crude oil will thicken with useage as the smaller molecules boil off when it is hot. Synthetic oil is not nearly as susceptible to boiling off since the molecules are engineered to be the same size. This is why synthetics perform much better in volatility tests (which measure thickening under extreme heat) than crude oils.

 

Which describes my wife's car and its usage perfectly. But it still didn't last the 10K miles, and I have the analysis to show it.
