I am very surprised to see it here on BITOG. Nice to see it performed so well!


Hello!

We have been using it for many years at my friend's BMW/MBZ shop. Great results!

Thanks to this thread, out of curiosity i looked for SWD Rheinol again.

I found out to my surprise that they have a big product catalouge in english, where they offer even some decent looking ester racing oils. In contrast, they only have a mediocre product range for germany, mostly aimed for thrifty customers, sold in DIY shops. Thats why this company is so unkonwn here.

My guessing is, they dont want to compete with the big ones like Liqui Moly here in Germany and are more focused on sales outside of Germany. Thinking about that Liqui Moly is the Nr. 1 for 10 Years in row now and most germans are very thrifty about engine Oil, this makes sense!

Thanks for the reply!

I am always glad to learn something about A/C in autos.

How much improvement have you seen in fuel mileage with the tune? I like what you have done with your car.

Hey, FrankBee3,

I think the tune is worth 3-5 mpg. The way the tune is written, is when vacuum is high and load is light, the mixture is leaned as much as possible and ignition timing is advanced up to about 50°-55° BTDC.

Once you step down for power, the mixture richens progressively with RPM and load and timing is pulled back to 25° BTDC @ WOT.

25° is where the 3 valve V8's make the best power on the dyno.

Hey, @ChristianReske,

Rheinol is a very good oil. Ive also used Liqui Moly and Total Quartz and was very pleased with them both. A friend buys two 55 gallon drums of Rheinol Primus 5w40 every month, so he refuses to charge me for Rheinol. Its hard to beat at that price!!!
