Mobil 1 oil filter, stock oil filter...

["Gerard van Vaugh" <gerard@acenet.co.za>]

Hi!

Mobil 1 seems to have finally arrived in South Africa.
Well, at least it is now advertised on TV. Mobil pulled
out of this country years ago and their stations became
Engen.

Anyway, here are the questions followed by the story:

    Do Mobil 1 oil filters out perform stock
    VW/Audi oil filters?

    Does the Mobil 1 have the same anti-drainback
    valve as the VW/Audi filter? (I assume it
    does 'cos it is "hi-tech" :) )

The story:

    My car (1990 200t) had lots of lifter clatter ever
    since I had the oil leaks fixed last year and
    switched to Duckhams synth oil. It also had bad
    oil pressure problems (<1 bar at idle, 3 bar at
    high speed). I changed oil 1.5 months ago to
    Castrol semi-synth and put in a new oil filter.
    Lifter clatter was gone, idle pressure was rock
    steady 1.8 bar and high speed pressures were
    where they were supposed to be. Now, recently
    after running hard the pressure will go down to
    <1.5 bar. The only reason I can think of that
    caused the original low pressure problems was
    the cleaning effect of the Duckhams oil that
    caused a huge clog of the oil filter. Perhaps
    the slow return of the problem with the new
    oil is the same thing happening. Since folks
    here had praised Mobil 1 oil for quieting
    lifters and giving good oil performance I have
    started to think I might try the stuff, but
    want to know more about the oil filter Mobil
    sell as it might be an improvement on the
    stock unit. I am thinking of using 15W50.
    Any experiences from listers on using this
    stuff in an environment with temps ranging
    from 5 celcius to 40 celcius?

Sorry for putting out another e-mail regarding
oils and filters. I know I;ll probably get some
"but I've mentioned this before" e-mails. :)

Thanks in advance.

Regards,
G.

PS: 200 gets new gas shocks tomorrow (perhaps)
    right out the stock rooms of Gabriel and
    perhaps 2 new front Continental CV90 tyres
    next week ... will probably make a big
    difference to the fact that when I hit the
    brakes the driver's side of the car is the
    one that seems to dive so much more. Y'all
    just couldn't believe the state of the shocks,
    tyres and brakes on this thing! :) New CV
    joints last week. New K26 and 2-pc manifold is
    still a dream, but only $325! :)
