You need to check the oil every week and top up if required, don't forget, these engines burn oil and don't like being run low - they will start to knock if run low on oil.

Check what oil you are buying.
"Castrol GTX High Mileage" is a 15W40, so I wouldn't use that at all.

Valvoline Max Life, in our banger at 110,000 kept her running fine.:): The final drive in the transmission clapped finally, but the motor still ran well?:):

the key is to just use a good quality oil of the correct spec and change it and the oil filter regularly and all will be ok :thumbs:

the high mileage oils are pretty much a marketing gimmick

Dunno' about that? The Yanks were smart with their lubrication oils and additives. Remembering of course the demo' with Wynns Friction Proofing.:rolleyes: Anyway, Valvoline claim their oil additives help keep old lipped seals flexible, and as it was very competitively priced, I used it, no seal problems, and whilst it may or may not have, I found it suited me fine.:):

Not all of it. You can get it as 10W40. I have used it in my 156 in the past with no problems.
I'm just going by the info from Castrol and they only list the one labelled as "High Mileage" as a 15W40. see here

Beware a lot of these products. These friction modifiers can be very corrosive.:eek:

The trouble with the additives or oils, I forget which base group, is that they soften the seals because they make them swell. I don't know if it is a problem, but I imagine it may work only for a while, or even accelerate the degredation of good seals.:rolleyes: :rolleyes:
