Red Line 0W40 meets BMW LL-98 and LL-01 standards and is SL/SM/SN+/SP 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. Red Line 0W40 is similar to the BMW 5W40 but is formulated for high performance engines. It's high temperature performance is on par with Red Line 5W40 but the 0W rating will reduce emissions and wear in extreme cold climates. Choose 0W40 oil for maximum efficiency in a daily driver or commuter car. For spirited driving in warmer climates a 5W40 or 10W40 will provide better protection. Our recommended oil change interval is 5,000-6,000 miles with regular used oil analysis.
Red Line oil outperforms the factory oil when it comes to strength 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. Red Line Oil includes the appropriate levels of anti-wear additives and ash content to ensure compatibility with factory emissions equipment.
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 shifting its focus to high efficiency oil formulas, the need for a high performance motor oil is greater than ever.
The following is a very general guideline for oil weight selection. Engine designs are different and engines change as they wear. We recommend a higher weight oil for high-mileage engines or engines that show signs of significant wear - usually one grade higher. "Max Efficiency" assumes no sustained running at high rpm.
