Well, i just got my 1st oil and filter changed from toyota airport motors lhr. Their setup was good. Went straight to service manager, who seemed nice. Costed me Rs 7630 in total which included 5 lit Taglon 5W-50 oil, filter and battery water. Got the undercarriage bolts etc checked, air & ac filter cleaned as well.
Felt two changes after the oil change. One, fuel average seemed to improve a bit. And 2nd, not sure if it was psychological or in actual, but felt acceleration and pick response a bit stiff. Not as smooth as it was with factory oil. I think both oils are different. I asked the manager why 5w50 and why not 10w30. He said, 1st couple of oil changes with 5w50 and then will shift to 10w30.
