I don't know much about about reading VOAs so I'd like a little help from you experts. Currently I'm running Castrol GTX 5w30 in my Toyota Tacoma 3.4l truck. It's all I've ever put in it since new and it only has 6500 miles on it now. I've changed the oil twice so far. I'm going to switch to 10w30 next spring and I'd like your opinions on which 10w30 shows the best VOA numbers. I'm looking to stay with dino since I change it about every 3000 miles. I'm thinking about picking up a 5 gal. pail of Rotella T 10w30. I have a friend who works at a truck stop and can special order it through their suppliers and give me a pretty good deal. How do you think their numbers look from their website... http://www.shell-lubricants.com/products/pdf/ROTELLA%20T%20MG.PDF Should I go through the hassle of a special order, or just go to Castrol GTX 10w30, or is there something even better (readily available and around the same price)? Thanks in advance for any help! I'm really hoping to get 200,000 out of this truck.
