Hi guys. Just recently purchased a XF45 awd with 144k and I am thoroughly impressed with the car considering it's age. Just ran seafoam through the crankcase just under 100 miles before changing the oil with 5.5 qts of Pennzoil Platinum High Mileage Full Synthetic 5w30 & 1 qt of Seafoam Full Synthetic Ultimate Oil Stabilizer to reach 6.5 qts in total. Ran Seafoam in the fuel tank yesterday just before filling up with 91 octane. Tomorrow I plan to run seafoam through the brake booster line in order to rid the engine of some carbon. Any tips for a new owner?
