Motor oil, anyone read this before?

i read this last night well about half of it, is really long... but from what ive read some of the main points the guy makes are:

"The gold standard is that all engines should have a pressure of 10 PSI for every 1,000 RPM of operation"

"It is time to dispel the notion that 0W-30 oil is too thin when our manual calls for 10W-30. A 0W-30 is always the better choice, always."

"It is said that 90 percent of engine wear occurs at startup."

its really interesting,,, but do you guys agree lol before i change my oil....

Where did you get this information? The reason I ask is because I believe it to be BS.

@ idle on a cold start-up, i see 100psi.... so no. fail.
@ idle once warm.... 25psi..... not exactly precise, but closer than previous.
just cruising @ 80mph (4K).... 65-75psi.
WOT.... 85-90psi.




so VERY VERY VERYYYY generally, it "kinda" works. but not really.

Re: Motor oil, anyone read this before?

90% of engine wear at startup is probably accurate. I know a lot of wear happens at startup. 0W is thin as hell though. I wouldnt go thinner then 5w-30 but I stick with the 10w cuz thats whats recommended. Car manufacturers will usually go as thin as possible with their recommendations to squeeze every last mpg out so I dont like going thinner.

Re: Motor oil, anyone read this before?

it seems like truth exagerated... I would say the engine wear thing is close (I've heard 80%), but I have also been led to believe that the bigger difference in hot/cold viscosity the less stable the oil and the quicker it breaks down... so 5w-30 would be better than 0w30 ny that standard... even cars like the new mx-5 use 5w20 as opposed to 0w20, so maybe it doesn't need to be quite so thin (I think 5w actually does better in certain wear tests...)... I have seen some super high mileage h motors that don't use much oil, (good oil and regular changes)... I'd stay with the 5w30 unless I lived in Siberia.

Ive seen several 300k mile Hondas and I doubt any of them used 0w-30 lol. Hell most of them that Ive seen are lucky to have oil in them at all let alone decent oil.

Re: Motor oil, anyone read this before?

The 0w-30 or 10w-40 rating has no bearing in how good the oil is as a lubricant. It is the API rating that tells you how "good" the oil is. The last letter tells you the quality. The most "modern" oils are API-SL.

The numbers just tell you the viscosity (how thick or thin) of the oil. I wouldn't use anything less than a 10w-40.

The engines in most of our 'ludes are getting on a bit and most have done at least 60,000 plus miles. With thin 5w-30 or 0w-30 oil all your going to do is increase it's oil consumption, (ALL engines use oil, and Honda admit the VTEC engines do use more oil than you normally expect from a "normal" Honda engine) thiner oil will get past the now 8-15 year old oil seals/piston rings etc a lot easier than something heavier. It will also make your motor sound like a bag of spanners, as the oil is as thin as cat pi** you will hear every valve open and close, every cam revolution and every rocker contact etc, that goes on inside your motor. The motor wasn't designed with ultra thin 0w or 10w oils. The highest quality oil when the engines were designed was API-SF.


Non of us on here are "driving gods" no matter how good we THINK we are, non of us "mortal's" would ever be able to notice the VERY tiny (your looking t maybe half or at most 1 HP) increase in power gained by using ultra thin 0-30 or 5-30 oils.

Do your wallet, your ears and your engine a favour. DON'T use 0w or 5w oils!!
