Planet 9

At last night's NNJR meeting reps from Total Lubricants gave a presentation on their motor oil. I spoke with one of the reps and he showed me some dyno charts indicating that the Total oil was running 10 degrees cooler than other oils. Saw letter from Porsche authorizing use of 5W40 motor oil. In NJ they will sell directly to us at a considerable savings when compared to Mobil 1.

Anyone using Total synthetic motor oil in your car?

FYI Elf is now Total. The Peugeot P1 ALMS cars are running Total motor oil (their diesel motor oil-a special blend).

10 degrees cooler than what in what?

RSR on dyno.
Rep will not reveal the name of the "other" class 4 synthetic oil. He said that he is not in the business of bad mouthing other companies. He will only speak about his product.

Farenheit or Celcius? I assume the RSR would have been tested at extremes which means that the temp difference would be magnified. At normal operating temp in a normal car the difference is probably smaller.

I was wondering what difference it would make in normal day to day driving if the engine was running a few degrees hotter or cooler?

Hold ON.....

I AM Sure We Have a ThermoStatically Controlled System that Makes Sure Our Engines are Running at Optimum Temperature........

Oil Running Cooler? Is This Snake Oil....?

I assume you mean Group IV oils by "class 4", which means it's a PAO (polyalphaolefin) based oil. Let's also assume the competing oil is Mobil-1 0W40. I suppose it would be possible to have lower friction mean lower oil temps; you can see this in differentials and transmissions, but kareldeeley has a good point about engines, and I think I'm on the same page. Royal Purple has made some similar claims in the past too, and they've even claimed power differences on a dyno. Does that mean RP is better overall for your engine? Maybe, but we don't know. There's more to oil than just friction reduction.

Oil, engine,...whatever. Does it make a difference if one is a little cooler or hotter that another under normal conditions?

Are you doubting the OP?

Optimum operating temperature usually has an upper and a lower limit. The measuring instruments in a car have a tolerance and aren't exactly accurate.

Yes, there is a lot more to oil than just friction reduction. The reps made that point too.

THE ORIGINAL QUESTION ASKED WAS: Anyone using Total synthetic motor oil?

That is all I asked and all that I am interested in knowing.

Remember in the days of air cooled engines, the engine oil did help to cool the engine. Lots of oil coolers in the older cars. Most of the racing Porsches that I have seen have engine oil coolers (along with transmission oil coolers!). Even in the water cooled engines, the oil will contribute to engine cooling. Last night there was a discussion of how hot motor oil could get and what can happen at elevated oil temperatures. Hence the comment about Total oil reading lower temps seemed interesting.

I agree that the oil temp in these cars would be thermostatically controlled. However, the temp of oil being returned from the engine prior to going through the cooler is not. There is still a temperature rise as the oil picks up heat from the engine. This is one of the functions of the oil as Pcay60 points out.

I don't know offhand whether the oil is cooled on the way back to the sump or on its way from the sump to the engine. Either way if the oil temp was measured prior to being cooled it could be useful and interesting data.

And to answer the original question I'm not using Total.
