Would I gain any benefit whatsoever if I switch to Mobil 1 for
my 2005 Hyundai Elantra with 21000 miles that already runs
butterly smooth on Castrol GTX 5W-30??
I plan on owning this car til 165,000 miles. Im a very conservative driver in the suburbs of central nj..not quite
city and not highawy, sort of inbetween.
I faithly do 4,000 miles OCI. At 5000 miles, I added Motor
Silk engine treatment to oil and the car runs and sounds
so smooth on acceleration all the time.
