I am nearing the end of my engine break-in period and want to switch from Pennzoil 5W30 to a synthetic oil. The oil I plan to use is Esso XD-3 0W30 or Motul 8100 0W40.
My question is, will a thicker oil (as determined by the cSt number) increase my fuel consumption compared with a thinner oil? Will it reduce power output? Do the benefits of a full-synthetic oil have any effect on this?
Pennzoil 5W30
cSt @ 40C: 64
cSt @ 100C: 10.5
Esso XD-3 0W30
cSt @ 40C: 71
cSt @ 100C: 12.1
Motul 8100 0W40
cSt @ 40C: 73
cSt @ 100C: 13.3
Thanks for your help
