I know you've all been anxiously awaiting my final decision on which oil to use on my first diy oil change...well, after much debate over syn vs. dino and much consternation and gnashing of teeth...I made the trip to wally world tonight and bought 12 qts of TropArtic Syn Blend 5W-30 at $1.47 each. Did I do good? I don't know, but I FEEL really good about, and isn't that really what's it's all about in the end, gentlemen? I just felt the C-P TropArtic was the best value with really good MSDS/PDS/VOA numbers based on all the BITOG research I did...a nice tradeoff of gIII syn/gII dino at a really nice price...oh and avoided all the orange boxes and went with a supertech filter on this first go-around (for my 2.4L Nissan Frontier and my 3.3L Dodge Grand Caravan). Just curious though - why so much praise for the 10W-30 with not as much love for the 5W-30? Like I said, I'm taking the plunge and doing my very first oil change on my own...curse you BITOG for what you've done to me...indeed for what I've become! And as the great american statesman Ace Ventura once said, "If I'm not back in five minutes...just wait longer!" Wish me luck!!!
