Almost everyone I’ve seen post UOA’s on 20 weight show higher levels of iron, copper, and aluminum. You can actually run up to 15w40 https://www.machinerylubrication.com/Read/518/motor-oils

I’m actually running nearly 96 octane, but yes, it obviously rears its head at partial throttle. I was under the impression it may be oil droplets causing the pre-ignition but apparently not.

As mentioned, it’s very minor and at tip-in. Happens before and after the tune at light throttle not WOT.

E20 is fine, not much more than this. Open loop actually runs on the rich side. Again, it’s more tip in knock under partial acceleration. Not under WOT.

December or January for the new 2.4

Correct.

That’s what I’m thinking too, combined with the hot IAT’s. OTT does not disable this mode in the tune.

Good to know, thank you. Would you recommend a better oil for this truck? I was planning on running Ow-40 in the winter. I’m in Atlanta so it’s on the hot side / mild winters.

Got it, so no reason to really change oil type?

I noticed it before the tune as well. But not a as much.

Well, I’m assume it’s LSPI as it matches up with the definition from what I understand. Light throttle, low rpm, higher load. I’m watching the knock sensors via my OBD2 device / Toyota PID’s. This engine makes all its power at higher RPM for the most part. Tends not to happen if you are heavier...

I just finished my personal break-in procedure on my 23 Tacoma V6 3.5. I switched to Mobil 1 European Formula 5w-40 at 200 miles, since then I have done 2 additional extractions. I’m also a big fan of Liqui Moly’s Cera Tec and just treated the motor at 1200 miles. It definitely helped smooth out...

If my differentials are torque vectoring vs limited slip, should I stick with 75W-90?

I Thank you, great advice. For the differentials, from what I understand my GT2 AWD is not limited slip but torque vectoring. This probably means I should stick with 75w-90 for both the front and back, correct? I am a little concerned about warranty as this 8 speed transmission is not known...

Gentlemen, recommendations for the best oil to use in both gear boxes? I’ve heard great things about Amsoil but at $33 a quart, pushing $500 in fluids alone, it’s a little absurd. Thinking about RedLine instead. Think the price is worth it?

Since buying new, I always do my first two oil changes early during break-in. 500 miles and then again about about 2k. I’m a firm believer this reduces microscopic scoring and produces a better motor. On this Smartstream 1.6t hybrid fuel dilution is similar so extended OCI’s are not healthy. I’m...

It’s good to monitor see if you are consuming oil.

My favorite

Not sure who that is.

2nd extraction. Car is a month old. 1700 miles. PUP 0W-40 - no filter change yet.
