Hello friends, Back again for more advice. Helping my brother chnage the oil on his vehicle soon and he has no idea what’s the correct oil to use. Luckily he has been using the correct viscosity, but buys whatever is cheapest. Can’t blame him for that. So , with that being said what oil do you guys recommend for the following application. 2002 Toyota 4 runner SR5 3.4 V6 165k miles OCI ~ 7k. Daily driver :20 miles daily Chicago Illinois Thanks!!!
