Newbie Question - Can I use Mobil 1 Turbo Diesel Truck 5W-40 oil in my 92 4runner (22re)?

Yeah it's all the same and if you read on the container it says it's great for gasoline engines as well.

But you should probably stick with the 5w-30 since that is what the 22RE recommends.

Any oil is going to be more or less the same for a given rating ie 10w30, 5W30 and so on the differences are in the additive packages. Diesel oil will have more ash disbursing chemicals then a gasoline oil for example. Synthetics will be different to dino oil which is different to mineral oils within the same group rating,{ but do not run mineral oils they have no added wear packages and will wreck an engine that is not designed for them lol}. I ran Shell Rotella T 10w30 diesel oil in my old 87 22R for over 200,000kms with no issues at all ever.

i would never run anything but rotella diesel oil in my diesel.. i hear gas oil aint good for them AT ALL!!!!
but i have in a pinched used sum of my rotella diesel oil in my 22re... worked good but i usually just put what ever is cheapest in it..as i drive it under 1000kms a year

You are correct T diesel oil in a gas engine no worries gas oil in a diesel? only in an emergency and changed out asap... because of that ash dispersant additive also diesel oils are formulated to handle the sulfur in the diesel which gas oils are not...

I've heard that diesel oils have a much higher detergent and anti-oxidation additive package - I was going to try some Rotella in my engine since the oil gets black so quick.
