Where di dyou get this information from?
Castrol and Valvoline have Product information Sheets on their website indicating that Valvoline falls 36 Degrees short, Castrol LMA falls 1 degree short..
Also, Castrol is listed on the list of fluid that Rover Oks for their products, valvoline is not on that list.
Did you read the link I provided? My bet, would be no.
At least read this one.
