What kind of 'oil' are you using??? - pmj4147 - 06-05-2014
i was using 10W-40 MB 229.1 stock oil, 5w-30 racing oil blablabla
but i can't find the right oil to my engine
(i ripped out metal-bearing few days ago)
guys in my hood are using Motul 300v 15W-40 or Omega G1 15w-50
kinda like that.
What you guys are using??

A bit on the side, but can Agip 10w-60 Racing oil be used?

I use mobil 15w-40 in my everyday driver 617.
In anything race or high performance, we run and I highly recommend Schaeffers Supreme 9000 5w-50 or Supreme 7000 20w-50.
I had a friend that has dyno proven that schaeffers makes more power on the dyno than other leading oil companies. My neighbor ran NTPA light pro pulling tractor, and when he switched to schaeffers he said the whole engine ran cooler and better.
I am not a sales person, I am just a firm believer. I have seen it proven many times

Summer, 15-40 Rotella, winter I use 5-40

5-50 synthetic is on sale here for $3.50/L should I stock up?

What do you guys think about using 10w60 racing oil?
RE: What kind of 'oil' are you using??? - Turbo - 06-29-2014
If the oil shall have some very good ability for load and special if the load is very high so there will be some contact between surfaces it shall have zink witch you do not find in normal oil if I am correct, but you can have no kat then

There are two things to engine oil:
- viscosity
- quality
Viscosity: less important. But should be chosen in accordance to a) manufacturers recommendations, b) climate conditions. The first bit, p.e. "15W" tells you about the viscosity in low temperatures; "W" for "winter". The next bit is the viscosity rating for warmer temperatures. The issues is that not all oils are rated at th same temperatures. But as a guide it's still a reliable figure.
So if you have, let's say an average temperature in summer of like 30°C, and often above 35°C - a 0W-40 oil is probably too thin. This oil however would probably work well in winter conditions. And so on and on. The higher the number, the "thicker" the oil. The higer the temperature, the higher the "summer" rating should be. At least W123s and W124s still have a handy temperature/oil grade diagramme in the user manual...
Next bit: quality, the API rating. The higher, the "better". I think MB does not recommend anything below API SF, which is pretty high up the range. Especially in a Turbocharged high-performance engine I'd look especially for a very high quality oil with high shear resistance. And also I'd use an engine oil that's rated for use with diesel engines. They usually have higher contents of detergents to wash out soot buildup in the engine (as we all know, diesel oil is pitch-black). API-CF is the highest diesel-rating. API-CC is the lowest and not recommended for turbo engines... High quality oil usually also have a lot more usefull additives. Detergents, stuff to improve shear resistance and to prevent the oil from carbonizing.
And then there's the choice of wheter to use synthetic, semi-synthetic or mineral oils... My opinion: at least semi-synhetic. They are usually of a higher quality. In my Mini I've used mineral oils - based on what "the internet" said. I've had high oil consumption. With semi-synthetic high quality oils the oil consumption went down. And that's another point: those high-tech oils are able to withstand higher temperatures without vapourizing.
Personaly I'm using an oil with added MoS2 (molybdenum disulfide) as solid lubricant. It's been used allready in WW2 to allow planes to land in case of emergency (oil tank hit) and allowed the engine to run for several more minutes without seizing... It's probably highly unneccesary in a 147HP diesel engine - but oh well.
I've used cheaper oil before - with this the engine also lost some oil leaks. Which is another point worth mentioning; higher quality oils often contain a good amount of additives to take care of old rubber seals. Oil consumption went down from 1l/10.000km to 0.
All in all - it's basically a semi-religious rocket-science to chose the right oil. What I'm actually sayin is simply put: buy the oil that suits you climate conditions (viscosity) and get the highest quality (API rating) you can.

BAMP!!! There it is... BAMP!!! There it is...
If only every single oil thread could end with that statement. If only...
I find it comical how some "experts" will dump a FOOK-TON of monies into their motor and then set off on some mission to discover the absolute cheapest motor oil they can run in that exact same powerplant! AND THEN wax on like a religious zealot about their findings to an all too receptive and game interwebs audience. Priceless. Wait, wait, hold on a second, I gotta get more butter for my popcorn.
OK, so appropriate weight for the climate and the best quality you can afford. Doesn't sound like rocket surgery to me. O, and one more thing. Just a minor addition. Keep an eye peeled for the snake oil salesman, there's always one. Us humans are needlessly easy prey.
