Hey Guys, My RDX uses PP so I was thinking of switching over to PP for my Prelude too. I only do 9000KM (about 6000 miles) oci on the prelude but it is winter driven as well. Reason behind the switch is ASL is about 100 bucks CDN where PP for 4.4L jug is about 22 bucks cdn , ASL I get about 12 L (bit less actually) and with PP for the same price I get 22L and I can feed both cars :) Only concerns is currently with ASL my prelude eats about 0.5L-1L every 9k (known oil consumer but no blue smoke!) so I was wondering if PP will negatively affect the consumption???
