Red Line 5W40 meets BMW LL-98 and LL-01 standards and is SL/SM/SN and ACEA A3/B3/B4 rated. These are characteristics published by the oil manufacturers and Red Line products share or exceed the minimum standards set by BMW. Use 5W40 in warmer climates where a 5W30 may prove too thin. 5W40 can be used in all applications calling for a 5W30, including all non-M engines from 1992-today. We have found that not all oils are created equal and where Red Line excels is in performance under stress.
The latest BMW oils are engineered for efficiency and include additives to enhance lubrication, reduce emissions, and improve fuel economy. But in the high performance turbo world we live in, these oils break down faster, leaving your engine unprotected. Red Line uses a higher quality base stock for its oil products that is superior at withstanding higher temperatures and stress than other oils. Redline oil has higher levels of ZDDP (zinc and phosphorous) and a higher HTHS rating so it does a better job of lubricating, protecting, and sealing in the hotter environments our turbo engines are capable of. This is especially important as engines accumulate mileage and wear as a thinner oil won’t be able to provide extra levels of protection. Even as oil heats up and burns off, Red Line oil retains more of its properties than the factory TwinPower 0W30 or 5W30. Red Line Oil includes the appropriate levels of anti-wear additives and ash content to ensure compatibility with factory emissions equipment. Our recommended oil change interval is 5,000-6,000 miles with regular used oil analysis.
Red Line Oil has proven over many years of use in our own track vehicles, race cars, and street cars/trucks to provide unmatched long-life protection. The more we learn about this product versus other competitors, the more we like it – Red Line exceeds our demanding standards. With BMW abandoning 5W30 for 0W30 and even 0W20, the need for a high performance 5W40 motor oil is greater than ever.
