I know it is a little early to tell, but I thought I would share some preliminary MPG data with you all.
I have a 2002 Toyota Tundra. My driving is like this: 5 miles to work, 5 miles home for lunch, 5 miles to work, 5 miles to home. We never use the truck on the weekends, it's a commuter only vehicle.
I was using Amsoil XL 5W30 and switched to Amsoil Series 2K 0W30 hoping that the oil pump would get out of relief sooner and possibly give me some mileage gains. I won't make a conclusion yet on the MPG, but the oil pressure absolutely gets to normal idle pressure faster. My oil pressure gauge was very high at idle with the 5W30 until I basically got to my destination in the morning. With the series 2K 0W30, It is at the normal idle pressure by the first stop light (about 2 minutes).
Even though I only put 5K miles a year on this vehicle, using this very early estimation, it looks like I will pay for the oil with the MPG savings (my math shows about 7% increase since the Series2K, about $75 over the life of the oil change). Again, two fillups is hardly concrete evidence but I was too excited not to share my findings thus far.
