Title: Oil Change Due
Post by: les smith on January 11, 2011, 09:26:36 PM
Hi All What is the difference between Dexelia Ultra 5W- 30 and Castrol Magnatec 5W-30? I use Dexelia but have to go to the dealer instead of local. I’m due a service and might order up Prolong 10W-30 from MRP. What would be best for my RX8 Thanks
