I am trying to decide between Mobile 1 5-W40 Synthetic or sticking with conventional Rotella 15-W40. Is it worth the expense to go with the synthetic? I change my oil about every 3000 miles. Thanks!
If you will still change it at 3000 miles even with synthetic, then don't waste the money on the synthetic, just use dino. Even the dino oil will last far past 3000. If you plan to go for longer intervals with the synthetic then it might be worth it.
I just bought 20 liters of Rotella T 15w-40 from walmart, 66$ for 20 liters isnt to bad i figure
