Used liqui-moly 5w-40 on my last oil change. Pelican parts 5 liter jug.

It's $36 per jug.

Car runs fine. No hiccups. Will have it blackstoned in around 5k miles. See what happens.

Btw car has 23k original miles. MY2001 C4 coupe Tip

I like to read about 100K+ miles with original engines in the 996. Post some more!

118k - M1 0-40. ~5-7k. DD. When I opened the engine @ 100k it looked brand new. When I change the oil it still looks golden. Will do oil test on next change.

not on our Saab, if you go over 3-5k the engine will sludge due to an inherent design flaw

100k and whatever I can find. I seriously doubt it matters as much as the pundits would have you believe.

luanta

wow, thats really low miles!!!!

fpena944

113k miles, use 0w40 Mobil 1 every 5k miles.

Actually it's even less than that when I DE the car as I will change the oil after each event. Might be overkill but I just feel more comfortable removing the crap that might end up in the engine after tracking it.

117K miles, original engine...0-40 Mobil1 Sweet as can bee

Well so far, the M1 0w-40 seems to have proven itself worthy for our babies. Anyone else out there beat the 157k mark yet? Please post. Thank you.

Mobil 1 5w40 (Turbo Diesel Truck)

runs good.

I use a cocktail of :
Mobil 1 High Mileage 10W-40 and Mobil 1 5W-40 (Turbo Diesel truck) every 5K miles.......60K miles.................

Lance 4c

What is the ratio?

pesuazo

1 Jug (4 quarts) of 5W-40 turbo diesel; 1 Jug (5 quarts) of 10W-40 High Mileage.....usually there is one more quart of 10W-40 (total 10 quarts)

135K miles on a 99C4, original engine, had it since 18K in 04 and I never paid any attention to what kind of oil goes in. The invoices from my Indy says Mobil 1.
