I've seen some pretty good reviews on Walmart's Super Tech Synthetic oil.
I've never before used synthetic oil in any vehicle I've owned....always dino oil, and my vehicles always ran well with no oil related problems. Even so, I'm pretty sold on synthetic now, especially since my latest vehicle, a 2015 Toyota van, calls for 0W-20 oil and newer engines often have tighter tolerances between metal parts. I may go with the Super Tech synthetic and pair that with a good oil filter. Truth of the matter is, it doesn't matter which brand of oil one prefers, as long as it's changed at the right time.
