Engine oil OEM Toyota or Lucas

I change mine every 5,000 miles and the oil is dirt black when I drain it. I have a Rav 4 with the same AR25 engine and I want my vehicle to last as long as possible.

It’s a fact that frequent oil changes are better than not. Anyone Toyota Master (NOT tech) will tell you every 5k and for good reason. Want to go by the manual and do every 10k? Go for it, but that’s insane. If you want your car to last as long as possible, change every 5k.

I’ll be doing my first one at 1000 miles, then I’ll be doing them every 5000 miles or 6 months.

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.

Toyota synthetic. I was going to do Mobile 1 but noticed a few claims of people using both saying it shifted a little more smoothly with the Toyota oil

My Miata has almost 300k on the original head gasket I started using the far right a few times ago and I don’t leak a lick of oil

I’m not going to argue with anyone about what it does but I’ve used Lucas for a long long time I have a 93 Chevy truck with 400k miles that I have never taken care of correctly I have run it out of oil overheated it overloaded it and abused and mistreated the engine in that truck and its still able to do any thing I need it to.

I use this on my 2003 Passat 1.8T probably every 2-3 oil changes. Motor has 269,000 miles and burns a smidgen of oil on startup. The Lucas seems to help a bit.

its really only an issue on track if youre running sticky tires. running 0.5-1.0qt overfill seems to be a decent solution on track

I installed an oil cooler on my buddy's 370z and he dumped in oil and a full bottle of this and I just scratched my head
