I've just done a oil, oil filter, air filter, change on my wife's car. I could swear it runs sweeter, and revs a little smoother. I've noticed this before from just an oil change. I could understand it from a spark plug change, is this in the mind or is it really the frictional difference between 4,000mile oil and new?

I can hear when ours needs the oil changing, and it quietens down after it - at the last change, Charlie could hear and feel the difference, but up until then she was a disbeliever! :)
I've noticed diesels (turbos in particular) always feel livelier after an oil change. Don't know what the mechanical explanation is (if any).
Way back, I had one of the first 1600 Sierras and that always felt massively smoother on clean oil. As the oil got dirty, you'd get little vibes through the gearstick and pedals at certain points in the rev range, and for about 1,000 miles after an oil change, they'd all disappear.

Interesting, I've had a couple of cars with that engine - covered about
100,000 miles in them. I do not believe you can hear/feel any difference.Tell me, do you believe that if you swap your speaker cables end to end, you get a different sound ? I mean, the sound is going down the cable in the opposite direction, right ?

You can definitely hear the difference on a transit diesel when you change the oil, & that'd only work with speaker cables if you're using OFC ones with linearly polarised crystal structure......

Never heard a transit diesel before and after - especially not under controlled conditions ( ie. holding other variables constant). As to OFC cables - please explain how swapping the direction affects the signal and what you hear - I've done listening tests and cant detect those differences. Hifi dealers say they can hear the difference - interestingly enough they are almost always non-musicians who are nearly tone deaf, unlike myself.
I am interested to know how the OFC cable works better one way on an AC signal......

They run better after a full clean too. Brush out and vacuum the interior, wash and polish the car, clean the windows. Always runs quieter and smoother afterwards. DaveK.
In addition to your suggestions, I usually find that an application of tyre-wall black really does make a difference, although I also think a nice clean rocker box and battery are the final touches to ultimate performance :-) Vroom vroom!

Transits are really obvious, probably in excess of 3dB at 60 mph, & the cables was me being grumpy after a couple of stupid HIFi arguments, the only difference I've ever found with speaker cables is more copper = better damping.
