What is the best engine oil for use in an Alpina B8 4.6 engine:
Castrol FORMULA RS 0W-40 (Race)
Quote:
Castrol FORMULA RS 0W-40 · SAE 0W-40 · übertrifft API SL/CF · ACEA A3/B3/B4 · VW-Normen 502 00 / 505 00 · BMW LongLife-98 · MB 229.1 · Porsche-Freigabe.
Castrol FORMULA RS POWER AND PROTECTION bietet:
Deutlich mehr Motorleistung - auch bei Motoren älterer Fahrzeuge kann sich, im Vergleich zu FORMULA RS 10W-60, eine Mehrleistung von über 5% ergeben.
Verbesserten Verschleißschutz - Tests unabhängiger Institute ergaben einen um mehr als das 3fache besseren Verschleißschutz im Vergleich zu FORMULA RS 10W-60, selbst bei extremen Temperaturen.
Hervorragende Fließeigenschaften - ein Motorenöl sollte immer so schnell wie möglich dort sein, wo es gebraucht wird. Aufgrund seiner 0W-Viskosität ist Castrol FORMULA RS 0W-40 wesentlich schneller an den kritischen Stellen im Motor als Castrol FORMULA RS 10W-60.
Or in English:
Castrol FORMULA RS 0W-40 · SAE 0W-40 · exceed API SL/CF · ACEA A3/B3/B4 · VW standards 502 00 / 505 00 · BMW LongLife-98 · MB 229.1 · Porsche release.
Castrol FORMULA RS POWER AND PROTECTION offers: Clearly more engine performance - also with engines of older vehicles, compared with FORMULA RS 10W-60, an increased output of over 5% can result. Improved wear protection - tests of independent institutes resulted in more than 3 times better wear protection compared with FORMULA RS 10W-60, even at extreme temperatures. Outstanding flow characteristics - an engine oil should be always as fast as possible, where it is used. Due to its 0W-Viscosity Castrol FORMULA RS 0W-40 is substantially faster in the critical places in the engine than Castrol FORMULA RS 10W-60.

Castrol FORMULA RS 10W-60 (Sport)
Quote:
Castrol FORMULA RS RACING SYNTEC ·
SAE 10W-60 · übertrifft API SJ/CF · ACEA A3/B3.
Castrol FORMULA RS RACING SYNTEC steht für eine außergewöhnliche Schmierfilm-Stabilität/ Stärke – selbst unter extremen Betriebsbedingungen im Tief- und Hochtemperaturbereich. D. h. ein exzellenter Verschleißschutz ist gewährleistet.
Castrol FORMULA RS RACING SYNTEC hat daher eine sehr hohe Akzeptanz im Motorsport, bis hin zur Formel 1.
Castrol FORMULA RS RACING SYNTEC reduziert den Ölverbrauch von Motoren auf ein absolutes Minimum.
Eine besondere Additiv-Technologie verhindert noch wirksamer als bisher im Hochtemperaturbereich die Bildung von Ablagerungen im Motor. Er bleibt sehr sauber und sein Wirkungsgrad dadurch stets einwandfrei. Die Schadstoff-Emission im Abgas wird niedrig gehalten.
or in English:
Castrol FORMULA RS RACING SYNTEC ·
SAE 10W-60 · exceed API SJ/CF · ACEA A3/B3.
Castrol FORMULA RS RACING SYNTEC has an unusual lubricating film stability / strength. even under extreme operating conditions in the low and high temperature area. I.e. excellent wear protection is ensured. Castrol FORMULA RS RACING SYNTEC has therefore a very high acceptance in the motorsport, up to Formula 1. Castrol FORMULA RS RACING SYNTEC reduces the oil consumption of engines to an absolute minimum. A special additive technology prevents the formation of deposits in the engine more effectively than so far in the high temperature area. It remains very clean and its efficiency is thereby always perfect. The pollutant emission in the exhaust gas is kept low.
Up until 1997 ALPINA recommended use of the 10W-60, then they changed recommendations to something else, I think it was 5W-40???
It actually looks like the 0W-40 product would be better for high performance engines like the B8 due to the lower engine wear?

Actually not, TWS MOTORSPORT 10W-60 is an oil especially designed for BMW M3/M5 and Porsche engines. It is in their program alongside with the RS products and is listed under their "Werkstatt" or "shop" products:

Castrol TWS MOTORSPORT SAE 10W-60
Leistungsklassen: API SJ/CF, ACEA A3/B4, Spezialfreigaben von Porsche und BMW - Exklusivfreigabe für BMW M3/M5 Motoren.
Das voll-synthetische HIGHTEC-Motorenöl in Motorsport-Qualität für leistungsstarke Motoren setzt Zeichen - Racing - Viskosität SAE 10W-60 - Maximaler Verschleißschutz durch extrem belastbaren Schmierfilm - Geringster Ölverbrauch und saubere Motoren durch hohe Oxidations - und hohe Temperaturstabilität - Mehr Leistung durch geringeren Reibungswiderstand - Turbo-getestet.
In English:
Castrol TWS ENGINE PORT SAE 10W-60 Performance classes: API SJ/CF, ACEA A3/B4, special releases of Porsche and BMW - exclusive release for BMW M3/M5 engines. Full-synthetic HIGHTEC engine oil in motorsport quality for high performance engines sets standars - Racing - viscosity SAE 10W-60 - maximum wera protection by extremely loadable lubricating film - lowest oil consumption and clean engines by high oxidation - and high temperature stability - more performance by smaller friction resistance - turbo-tested.
So it looks like this was designed especially for the M5/M3 engines for BMW. Maybe due to the initial engine oil problems with the M5?

Castrol FORMULA SLX protects high engine cleanliness and prevents the formation of deposits - important for a permanent and problem-free function of the engine. Castrol FORMULA SLX saves constantly and continuously fuel, during the entire period of the oil change intervals
Well, the SLX0W-30 doesn't have the high temperature stability of RS 0W-40 or RS 10W-60, but it also seems like the film strength isn't as strong as with RS 0W-40 or RS 10W-60.
Send me your address per email and then I will contact Rene Bichler again.
Cheers,
Michael

This is good timing, my car goes in for its first service under my ownership on Thursday. What oil would you recommend the 0W 40 or the 10W 60???
Alternatively, what have you been using on your fleet of cars?
Regards
Paul
Hi Paul,
I have been using the RS 10W-60 on my cars so far and have been satisfied, but I will change to RS 0W-40 if I can get official approval from Alpina in Buchloe to use this engine oil. I suspect this will be no problem. I will probably have an answer in a week or so.
Your car has a silvery label in the engine compartment where it says something like "Alpina emphielt Castrol..." and then the oil type. What does it say? What about your B8 owners manual? (you did get one with the car, right?)
Whilst I do not have any technical basis for this I think care should be taken in the use of modern thin oils. This issue was discussed at length on the E34 M5 site. I recall |Raymond had some useful info.
I used Mobil 1 0W40 in my M5 3.8 and found after a hard run the engine tapped; a 944 I had also lost oil pressure with it.
I swapped to Mobil1 15W40 and this effect went. I have also used Silkolene turbolene GTi which was fine.
I use Silkolene 10W50 in the Biturbo and that seems fine.
The guy who runs my racing car never uses 0W oils especially in high power turbo cars due to the loss of pressure at high temps.
The query I have is why the lower figure seems to affect the high temp performance?
The best engine oil?
