silkolene pro-s 15W50 ??

[marcoturbo]

Hi,

I seek some feedback of 944 turbo owners about this oil (or the pro-r).

I currently run Motul 300v (15W50) which is ester based but its longevity is an issue. It breaks down quick (turns into black) and should be drained every 6 months... After all, it's a racing oil.

So I seek for a better alternative for my use (street/road - 4000 miles a year - Vitesse Stage 3 kit) with a good protection (ester base - high HTHS level) and correct drain interval.

The Silkolene looks to satify my requirements but this brand isn't well known here in France.

Thanks in advance.

I've not used it for 25 years in my bikes and my cars have never been "good" to warrant the expense but Silkolene has a very good name over here as a top end and speciality oil supplier.

Silkolene / Fuchs oils are excellent and the product youve mentioned is superb. Ester/PAO based oil should last way longer than six months though - synthetics were developed as long-life oils, after all!

Hi

Do not panic!

Dark oil does not indicate the need for an oil change or that it has broken down.

Modern detergent motor oil suspends minute particles in the oil. These minute particles cause the oil to darken quickly. Especially so in diesels. Also, look at modern car exhausts tailpipes. Before unleaded petrol they were grey, now they are soot black.

A non-detergent oil would stay clearer than a detergent oil because all the soot and deposits are left on the internal engine parts and create sludge. If you`ve ever taken a really old engine apart you`ll see lacquer and sludge everywhere. A more modern very high mileage engine might have some lacquer but little sludge (also caused by using cheaper oils)

Good oil should get dirty quickly as it does it's work cleaning the engine. The dispersant stops all deposits.

Modern machine tolerances and computerised assembly ensures minimal swarf which was why in the good old days you needed magnetic sump plugs and an oil change at 1000 miles but micron filter technology traps most things these days.

Modern cars and vans have up to 20,000 miles to 1st oil change so they do know something about oil and how it works as the intervals will probably have a safety factor of 2 or 3 built in.

Rubbing old oil between thumb nails is an old trick, you`ll soon feel if it isnt lubricating or has broken down - unlikely these days!
