The 4Runner's engine has never missed a single beat.

During warranty, OCI every six months or 7500 miles.

After extended warranty, once a year or 10K miles.

I wouldn't overthink this engine... it's THAT good on oil.


What is that supposed to tell you? ANY engine will run fine with ANY 5W30. The goal of BITOG is to find the best oil. Apparently, all oils are not created the same. All grades are not the best for a particular engine. You might find better result with xW40 in you engine than 5W30. But none of them, even the worst oil would kill your engine in 100K miles.

There is no such thing as best oil.

And, as long as it has oil, the 4.7 usually just keeps on going. I'd worry about the radiator, waterpump, and timing belt.

Match the oil grade to your weather and driving style.

Guess we are all wasting time here. And oil companies are stupid wasting money employing armies of chemists.

Maybe you are? But most oil is blended to meet a spec.
And, how would you describe as best? Oil that has the longest lasting catalytic converter or DPF or o2 sensor? or best MPG? or least consuming? or least wearing?
or best TBN retention? or best NOACK? TEOST? HTHS?

Get a clue
