TundraGeneral discussion forum for the 2007 and later Toyota Tundra.
This is a discussion thread titled "RPM's lower while freeway driving?", within the Tundra forum, part of the Truck Forums category.
2007 DC 5.7 TRD. I swear before while on the freeway while doing 70-75, rpm's would be around 22/2300. Now while on the freeway I can do 75 and rpms sit at around 1900. Did my engine get flashed at the last dealer oil change? Seems to be running fine without a loss of power.
