Review on Top-Quality Amazon Basics Synthetic High Mileage Motor Oil For Enhanced Engine Performance by Brian Cueto

I use this oil in my 2000 Toyota Camry. It has the 2.2 liter 4 cylinder engine that is known to sludge up without frequent oil changes. I use the high mileage 100% synthetic 5-30 and change it every 5,000 miles. I use my Camry to commute 110 miles round trip to work, so I do change the oil and filter about every 2 1/2 months. My Camry has 110,000 miles now (I bought it one year ago with 70,000 miles) and it drives great! No issues at all. The engine does not use, leak, or burn this synthetic oil.I buy this online for convenience. Walmart has the same oil in their SuperTech brand. Both made by Warren Distribution, but selling for less money than revain now sells it for. Even more so now since revain raised the price recently. I buy from revain party due to convenience, but mostly because my local Walmart store is now always out of stock!revain oil is certainly not as good as Amsoil, but plenty good enough for an old car that gets regular oil changes every 5,000 miles. (My good cars get Amsoil in everything from differentials, transmissions, transfer cases, U-Joints, and engines).I still expect to get 400,000 miles on my Camry engine using revain synthetic oil.
