Bro,
The question of whether to use synthetic or semi synthetic oil often comes up among BMW car forumners. US Consumer Reports ran an extensive test on the two types of oil, altering amongst many different brands. The testers installed freshly rebuilt engines in 75 taxicabs, and then ran them through the harshest conditions on the streets of New York City. Placing different brands, weights, and formulations in the cars, they racked up 60,000 miles on the engines, tore them down, measured, and inspected the engine components for wear. The oil was changed at 3,000 miles in half of them, and the rest were changed at 6,000 miles. results: regardless of brand, synthetic or dino, weight, and oil change interval, there were no discernable differences in engine component wear in any of the engines. Their conclusion? Motor oils and the additives blended into them have improved so much over the years that frequent oil changes and expensive synthetics are no longer necessary.
Based on the above statement, i choose among the cheapest Semi Synthetic oil in the market, Bardalh, priced at RM60/ 4 liter and change oil every 7500 km. No need to use expensive oil as its only a marketing strategy. Bardalh oil is form USA and of high quality, distributed by our Cycle and Carriage Bhd.
