I achieved the setting of knowledge. There is nothing worse or more dangerous that little knowledge being used o make sweeping statement. Eg 'Individual case patterns ' are hardly a case for conclusions. But hey I must be that moron in the lab

There is no well fact they suffer with fuel dilution. I haven't seen it even on race cars like MBs nor my AP1 running beyond the 9k intervals. Even the shear conditions of 9000 rpm and valve train gears have little impact on shear stability of the oils once we look at viscosity of oil with fuel and water boiled off. Even with 4% fuel the oil is well within the design specs of the engine.

This oil burning at x miles is a theory my russian colleagues like to have. So we ran a field trial around Moscow on 35 cars. . After 1million km I still haven't seen any data to support this theory. All that happens is the oil is consumed in the engine in the early stages of the odi, at the same time water and fuel accumulates (especially with ethanol boosted fuels). Water and fuel then hit a natural saturation point and the oil cannot hold anymore. Suddenly the oil level drops. Not because the oil is dead but purely the mechanism of fuel and oil dilution means the oil is 'full' and so the natural consumption of the oil becomes more obvious.

I see it in every case. Additives start to dilute,then you hit the tipping point, additive elements stabilise and oil consumption 'increases'.

But hey. I'm the moron as I can't make conclusions from individual cases

Ah but, I along with a good few NW chaps running pre 2002 AP1 management all suffer with the same issue, they're mapped differently to the later models due to insufficient under piston oil cooling. Using fueling as cooling instead of better banjo bolt / oil jet design found in the later models.

Just for my 2p's worth. People mention never hearing of engine going wrong because of cheap oil.

The problem here, for me at least, is that there is no way one person can test this (not with out some serious effort). You have to trust the spec sheets.

If some guy says to me this part will give me X more power, i can fit it and dyno it and i have a fairly reliable test to say this part is good/bad.

Now look at oil; i put Castrol Edge in and car runs, drives no issues. Next change i put some cheap oil from Halfords in and car runs, drives no issues. So what have i concluded, oil make makes no difference? NO, i've discovered the engine wont go wrong on one service interval of cheap oil.

Even if someone says "my engine shat its rings at 100k" and he used Halfords oil, you cant say it was the oil. You could guess.

This annoys me as i have no way of proving to myself that paying the extra for the "good" oil will prolong the life of my engine, or if changing the oil more often will be better or worse.

Have to go off what manufacturers say, and they side with themselves. BUY HONDA OIL. Every oil company says buy their respective top brand of oil.

Just bought 3 tubs of this stuff oil change very soon

HONDA don't make oil.

mikey k

NONE of the car makers do
They come up with a spec based on additions to an ISO standard and claim it as theirs (BMW & VAG do this alot)
There are stringent specs for oil "grades" to these ISO standards, what you don't get with the cheaper oil is additives over an above teh ISO grade that the likes of Castrol etc add to "create" their brand

Honda use Castrol oils now anyway
