recently i started hearing a whining sound in my 2000 accord ex v6 starting at about 2k rpm and continues through the entire gears i think all the way till maybe 3rd gear? (havent really payedthat much attention)that almost sounds like turbo or s/c but it doesnt have either, and it started just after i began putting shell v-power gas into my car a few days ago. anyone know what it could be?

 

Check for fluid leaks at the Axle seals on the differential
