While, there are many motor oils that meet, or exceed, the API (American Petroleum Institute) requirements for use in BMWs and MINIs, many BMW and MINI owners prefer to adhere to the BMW specific “Longlife” specifications, to include; the obsolete Longlife-98 and the current Longlife-01 and Longlife-04 specifications. In reference to these specs, there has been some level of confusion. Let’s take a quick look at the three Longlife specs:
BMW longlife (extended oil change intervals) approved oils. Typically called out for BMWs through 2001. Superseded to Longlife-01.
BMW longlife approved synthetic technology oils (BMW and MINI branded oils are Hydrocrack oils … not full synthetic). Typically called out for BMWs and MINIs 2002 on (with some exceptions). Also for use where LL-98 was originally called for.
BMW longlife approved synthetic technology oils (BMW and MINI branded oils are Hydrocrack oils … not full synthetic). Low SAP (Sulfur, Ash, Particulates) formulation, required for Diesel models with Diesel Particulate Filters (DPF). Can also be used in all gas & diesel engines that do not specifically call for LL-04 oils.
DON’T IGNORE NOISY HYDRAULIC VALVE LIFTERS IN YOUR BMW OR MINI!
Most later model BMW and MINI engines employ hydraulic valve lifters (or tappets). The hydraulic lifters use oil pressure to adjust a plunger and take up all the clearance in the valve train (vs. a mechanical lifter which must have a specific clearance periodically adjusted). This helps to ensure less engine noise, less maintenance cost and longer reliability, due to less wear and tear.
Hydraulic lifter can wear and not properly hold oil pressure, resulting in a tapping noise from the valve train clearance now created. Similarly, the small oil holes and passages within the lifter can clog due to oil varnishing or sludge build-up (all too common with today’s hyper-extended oil change intervals). The valve train clearance created by a worn or clogged hydraulic lifter, is what causes the typical tapping noise. Not only is the noise annoying, but more importantly, it can result in increased wear to the camshaft lobes, rocker arms, valve stem tips and the lifters themselves.
Replacing hydraulic lifters is usually a rather involved task and can cost hundreds of dollars. The most common fault in a noisy lifter is clogged or restricted oil passages. Liqui Moly Hydraulic Lifter Additive is specifically formulated to clean the lifter oil ports and passages, returning the lifter(s) to full operation and quieting the tapping noise and preventing the potential valve train damage.
Simply add one can to a fresh oil change and run the engine through the normal oil usage cycle (5000 to 7000 miles, using a high quality full synthetic oil, such as Liqui Moly). The noisy lifters should quiet down as the miles go by. Stubborn lifters may require a second application.
BMW is performing a recall on various X3 G01 models from model year 2018. The outer rear turn signals may flash red while the inner rear signal lights flash amber. This condition may confuse following drivers and does not meet the Federal Motor Vehicle Safety Standards.
G01 – 2018 X3 30iX & M40iX
According to the recall:
“Turn signals that flash multiple colors may confuse other drivers, increasing the risk of a crash”
BMW will inspect the rear turn signals and repair or replace as necessary.
The recall is scheduled to begin August 13, 2018. Owners of affected vehicles are being notified by BMW. Further information can be obtained by contacting BMW customer relations at 1-800-525-7417.
