Putting this Porsch Classic 10w50 engine oil in my 88 924S. As its a relatively new oil has anyone used it here ? Any feedback >?

 

I've been using Liquid Moly 10w60--a pretty modern oil I think--for ten years and over 100k miles with no obvious signs of a related problem. I would assume a Porsche classic-branded oil is even more safe

Curious who makes it. I know Total of France has a 10w50

 

Lovely can.

 

Curious to hear the experience with this oil. I

I was also going to give Driven GP-1 20w50 oil (semi synthetic) that a local pcar shop recommended. Thoughts on that? 87 944 turbo here.

 

There is a very strong suggestion that these engines need "old world" oils and that new modern oils are not good. Something about ZDDP additive. My experience with a modern oil has been great so far... but I mostly street drive daily (not track) and also need something to handle wide temp swings (witness last two days of frost -2 C and then +10 C today followed by +17 C by week's end)

The question is what kind of action the car will see

 

I have a 1988 Turbo S. All I've used is Valvoline Racing 20-50 or Mobil 1 15-50. Runs really well, uses less than 1/2 quart every 5,000 miles. Turbo has no play @ 157K, the engine is original but for the random oil seals. Replaced the oil pan gasket a few months ago along with the rod bearings, the engine had no sludge, oil pan wiped out clean with just a rag, and rod bearings actually looked really good but for 1 corner of one bearing that had minor wear. I replaced them all. Oil pressure @ 5 bar at startup, 3.5 - 4 bar when warm. Really happy with both these oils. When I used to DE with my car, did use more oil at the track but nothing too dramatic.

 

Is that Valvoline 20w50 synthetic or regular?

I'm at 171K and I haven't done rod bearings even. Maybe I should?

 

Dan,

Dino oil on the Valvoline VR1 20-50. I've had really good luck with it and lots of ZDDP. I change it every 3,500 to 5,000 miles. Lately, its been more of 2,000 to 3,500 miles with VR1...5,000 was when it was my daily driver and I used Mobil 1.

Well, on the rod bearings I don't know. I had to do an oil pan gasket and did the rod bearings while I was there. The oil pan gasket was involved, so I did a bunch of things while I was in there: AOS seals, new rubber hoses for the AOS and under the intake, new alternator (cause I had one sitting around - original was fine), new exhaust seals, new front engine oil seals, new belts/rollers, new water pump (you can do rod bearings without the front of the engine being serviced), new speed and reference sensors, alignment...you see where I'm going here.

The oil pan gasket requires removal of the exhaust crossover, intake, crossmember and control arms...so its a bit of effort.

 

I have been using Mobil 1 15w50 full synth for years in my 1988 924S but its no longer available here and ordering engine oil from abroad is not allowed due to flight restrictions etc... I trust the Porsche 10w50 is well designed for the 924S/944 engines and will not pose any issues or whatsoever . I am wondering if anyone has used it . Porsche Centre Athens has just opened so I have to wait for my oil service till 5th June ( oil, oil filter, air filter, brake fluid and brakes bleeding etc.). I am keeping the cans btw , they look fantastic

 

So success with dino oil 20-50w VR1?

When you used Mobil 1 was it dino or synthetic blend?

 

I should buy a can just to put it on display...

 

I'm using it and love it. There is seal conditioner in the mix which helps condition seals to prevent leaks. No noticable valvetrain noise on cold starts. What puzzles me is that it's technically motorcycle oil. If the factory suggests it, I don't see any downside.

 

Radmd74, yes the Valvoline VR1 20-50 is dino oil. ZDDP is high and I've had really good luck with it. Mobil 1 15-50 is full synthetic.

Jimbo, that's interesting as I use a blend of Mobil 1 15-50 and Mobil 1 20-50 motorcycle oil to increase the ZDDP on my 993 (as recommended by a 993 expert who owns a well known shop that specializes in 993s).

Long story short, I think there are many good oils which work well in both the 951s and 993s (and probably a lot of other types as well)!

 

Great stuff. I was a bit concerned with engine noise at cold start with this 10w50 when compared to the 15w50 so its good to know that this Porsche oil doesnt reflect on this concern of mine.

 

Which 944 are you using this oil for? Any unusual consumption with this oil or leakage?
