Question: Motor Oil for a Triumph BonnevilleI have a 2005 Triumph Bonneville. The factory recommends Mobil 1 Racing T4 fully synthetic API SH or higher and JASO MA, 15W-50. Locally I have found Mobil 1 Extended Performance 15W-50 that meets APISL/CF but does not mention JASO spec. Does this satisfy the factory specifications? If not please recommend the specific Mobil 1 product that does. Thanks for your help. -- Paul Weidmann, Boulder, CO
Answer: Mobil 1 Racing 4T 15W-50 is marketed specifically for Triumph motorcycles. Another choice is Mobil 1 V-Twin 20W-50, which is designed for motorcycle requirements and may be more widely available than Mobil 1 Racing 4T 15W-50.
