just recently I tried some of the new PYB 5w30 in my car. Well,I guess my RX doesnt care for the beloved YB Conventional oil. Immediately after driving it (had Kendall Synthetic blend in it prior)it seemed doggy! I thought it just had to get used to the change in the different oil`s. well after 3800 miles,it still felt like it was holding back so to speak. So I decided to try the new Ultra. Man what a difference! so much peppier,smoothness/quietness about the same. But is it ever cleaning up that motor inside (according to the dipstick) it`s been in for about 1500 miles,and the oil is a dark amber color already
This does not make me real happy though,as I was going to just use the YB for 5k runs. I thought about clearing the ecm (when the YB was in it) but I didnt, maybe it would have adjusted better to it I dont know. But after thinking about it,according to the car`s portfolio,It`s never had a full conventional oil in it! only the dealer oil of choice which is Kendall Synthetic blend.What do you all think about this rather odd experience?
