Customer Satisfaction Program. On some vehicles equipped with a 6.6L gasoline engine (RPO L8T), the original equipment engine oil dipsticks were incorrectly calibrated and the information in the vehicles? owner manual regarding oil capacity during maintenance is inaccurate. As a result, it is difficult for technicians to refill, adjust and measure the engine oil level accurately during vehicle maintenance. Dealers will replace the engine oil dipstick and print and insert a copy of the corrected owner manual page into the glovebox.
