Heating up the list - oil for our older Audis

[Kunz, Bob]

A short article in September's European Car discussed how ELF is
bringing their products to the US market. Low and behold our own Dan
Simoes is on their distributor list. But that's for my newer Audi. What
about my '86 5ks that has lived its life on Mobil 1 15w-50 since it's
second oil change?

 

Mobil decided to move their 15w-50 into the extended group and
discontinue it out of the regular Mobil 1 lineup. I've been changing the
oil and filter every 5k miles. This car now has 145K on it (a youngin')
and of course still runs great. I have a few noisy lifters but nothing
else.

 

I used 15w-50 because that's a weight in the owner's manual that covers
my temp range (20 to 110 degrees) and this car usually goes a year
between changes so it sees all of those temps. What about 10w-30? 5w-40?
Your recommendation?

 

I would say not to use the 0w-40 (I use that in the TT since it's 502.00
and 505.00 approved) cause it's too thin in this older engine.

 

Opiniions?
