Best Engine oil for Toyota 4runner

Amsoil engine oil

5000 miles with a quality full synthetic will serve you well for the life of your vehicle.

I did Amsoil once a year about 8 or 7k miles since I live 3 miles from work, decided and went with Penzoil every 5k miles on 2014 4runner. is cheaper and better than toyotas mobile oil

I found a dealership that sells the Toyota oem at 5.90 a quart so that’s what I use. It’s made by Mobil 1 but has certain additives added specifically for Toyota specifications that regular Mobil 1 doesn’t have. Technically it’s what the 4Runner will run best with.

I used Costco’s 5w30, Walmart Supertech Synthetic and Chevron Supreme semi-synthetic. The latter is my favorite. I also had Blackstone do a UOA(used oil analysis) and my engine and oil are all in top condition.

I've run Pennzoil Ultra in 5W-30 for the past 4 years and never had a problem.

I run Mobil 1 5w30 and still change it every 5k. I could probably bump it up to 7500 or 10k but don't because I do it myself, and it isn't a huge cost or inconvenience to do it early.
