So expensive engine oil really does work.

Just reading through a review of Millers nanodrive oil in one of my car mags, and they make some big claim about it. At £70 for 5 litres it would need to be! So they use a focus st as a test car and start of with halfords oil as a control, do three dyno runs and make sure everything is consistent. Next comes the Millers oil, and feck me! At 2750rpm they get 44lb/ft more torque! And over 20bhp extra! Across the rev range, gains are between 10-20bhp from 2k and 41/2k.

Wow.

Going by the article, readers car used and all done on the same day. Three runs done every time to make sure results are consistent. Amazing results like.

The article is in Fast ford haggis. Don't think I'm allowed to take a pic and post it up

Funny that - they seem to be sponsoring the magazine as well?

Cheers for the link. I've entered the comp

Just having a look at the dyno graph, and top of the rev range power and torque is the same as running the halfords oil. Both oils were 5w40.

did the same test a few years back and got very similar results between 5W40 and 15W50 (at the same oil temp)

pretty much what you would expect, it's not so much about change in friction as the extra load on the oil pump to shift thicker oil about (something that's very significant on modern variable cam engines that have very high capacity oil pumps).

you can get the same effect by dropping the oil pressure too, but once again, this has risks (if you go too far), hence the reason in F3 etc, the oil pumps are sealed too!

like I said, if somebody wants to provide the oil(s) I'll quite happily do the testing in a controlled environment...

Enter the comp and win some I'm sure PH would get free samples if they were to do a similar article. I'm gonna have a wee nose in the Vauxhall mag cos they said they done the same testing as fast ford but with a vxr.

LOL, yes right, I'm just a total looser

(and how is anybodies driving going to affect how something performs on a closed dyno test?)

Don't know what you mean fella.

People crying Bs! Where's your data? Never managed to get a look at the vauxhall mag many moons ago but FF mag do good comprehensive tests and personally I would think its genuine.
