ultra!!!!I just purchased a 2013 VT with 102K. I am going to be doing an oil change for the first time. Can anyone tell me if Pennzoil Platinum is a good synth to use and if so which one as there is Pennzoil Platinum, Pennzoil Platinum Euro, and Pennzoil Platinum Ultra. All three are currently on sale for $32cdn or less at my local Canadian Tire.
