Mileage drop issues with Nissan Mocco 2007, advice needed
I took my mother's mocco for a routine check at about 80k kms. Had the following done:
-Engine oil changed (Earlier was Havoline but it wasn't lasting even 2500 km so tried Kixx on a friend's recommendation)
-Spark Plugs Changed
-Transmission Oil was changed
-Coolant was replaced
Now the mileage has dropped from 15 km/l (With A/C urban drive) to about 10 km/l (with A/C urban drive) and the car feels heavier too
No Throttle body was not serviced. The Oil was 20/50.
Could wrong kind of spark plugs be causing this?
oil is too thick IMO and knowledge, these 660cc are designed to take 0w-20 or 5w-30( written in manual as well as inside the bonnet), I think i repeat i think max u can opt for is 10w-40. Hope it might help, rest wait and see the senior to come to help.
10w-30 may be fine in current summer conditions, but still too thick for winters. I use 5W-20 in all weathers in my nissan sunny and never faced a problem. Excellent mileage figures even from 1500cc engine on a sedan.
