I have 3 cars:
'97 Toyota Camry 4-Cyl
'00 Honda Odyssey VTEC V6
'03 Honda Civic VTEC 4-Cyl
When I changed from Dino to M1 5W-30 in Jun-2004 I noticed that all of them did not rev as freely. Several others on BITOG commented on having the same experience. I am not a racer, just a middle-aged guy driving around town, so this was not a problem.
In the last 2 days I changed the oil in all of them using the new new M1 GF-4 / SM 5W-30. I was surprised to observe that they all rev more freely again!
