Hi all,

I have a 2003 A4 which runs the variable servicing (in europe) and my
car has been run on Castrol SLX Longlife II oil.

I have recently attempted to buy this oil to top up, and have learned
that it has been replaced with 'Castrol Edge' oil which allegedly
replaces the SLX. I was told that I should use Castrol Edge 5W-30
which, as it says on the bottle, 'replaces SLX Longlife II'. I am
unsure however for the following reasons:

Castrol SLX Longlife II is 0W-30 and the Castrol Edge replacement is
5W-30 i.e. it is a different viscosity.

My Audi Service Manual says I need to use oil which meets the
specifications VW 503 00, VW 503 01 for variable serviceing. Castrol
SLX Longlife II indeed meets this as it meets VW 503 00 / 506 00 & 506
01, however The Edge oil meets the specifications VW 504 00, 507 00
??? totally different it appears?

Incidentally, there is also a 0W-30 Edge oil which meets VW 502 00/503
01/505 00 so I would have thought I should be using this???? this does
meet the spec in my manual.

Any help/reassurance would be appreciated.

My A6 2002 V6 2.4 needs VW 503 00 or 503 01 oil. I am using Mobil Rally
Formula 1 0W-40, which meet s the 503 01 standard.

For me it looks that if you want to stick with Castrol, you should be using
this Edge 0W-30 which meets the 503 01 standard. This is proper oil for your
car. Of course, any oil meeting the 503 00 is also fine.

The reason for using 5W- viscocity might be the oil consumption. My A6 2.4
is also consuming quite a much oil, around 1 litre / 3000 miles. It may be a
good idea to try something thicker.

Of course, 5w-30 is no thicker than 0w-30.

Don't work the wrong end of the number.

Any xxW-30 is the same viscosity as any other xxW-30 at operating
temperature.

[spare-me-spam]

Viscosity is just one oil characteristic.

Assuming that the manufacturer specific approvals ( MB229.x, VW50X.XX,
BMW LL-01, or whatever, for example), are met, If ( again, example)
10W-30 is spec'd, then 0W-30, 5W-30, 10W-30 are all fine.

The mfr specs involve the composition of the additive pack, and reflect
concerns about corrosion, sludge, specific metal wear, emission control
longevity, oil endurance, etc.

I don't know of any one place on the web to reference the ratings and
approvals, but it must exist, I guess.

| Incidentally, is there anywhere on the web an idiot's guide to the
VW-Norm

using

but

|
| Also is it safe to assume that 500 00 [or whatever] (1/97) is better
than
| 500 00 (1/92) - i.e. are the later dates always a more exacting
standard?
|
| Again, I presume that zzz 01 is always OK if zzz 00 is specified, but
that's
| only my assumption.

Just put Mobil-1 in your car and forget about other specs, etc. It's Audi
and VW-approved.

Look, 0W-xx is STILL thicker at startup than 10W-xx is at operating
temperature.

If oil consumption were a concern in the time between startup and the
few minutes it takes to get to operating temperature, oil consumption
would be spec'd in quarts per start, instead of quarts per 1000 miles.

I'm sure there are some engines that have a higher usage rate until they
are warmed up, but its unlikely to affect consumption overall.

| True - but I wonder when our cars use oil - when they are cold, or
