I've been using Valvoline MaxLife Synthetic 5w30 for a short time in a Toyota 2UZ-FE (4.7 V8), which has had immaculant maintenance. I'm curious about trying Castrol Extended Performance and going 10,000 miles or annual coupled with a fram ultra. Seems like a very robust oil, but not many followers here. Thoughts appreciated!

Without a description of driving conditions can anyone make informed advice?

My friend has a 2002 2UZ-FE and short trips mostly; with 6.5Qt sump, 10K-12K about what I stretch it out to with extended drain oils (M1 EP, amsoil)

A 3 mile jaunt doesn't get those 6.5qts too warm....
 
How does your maxlife synthetic look at your 5K OCI now. A UOA would tell you. It could likely go 10K. The other oils are for 15K+ miles.

If its all highway miles, no problem. If its city miles or hard haullin, either stick with the 5K mile or step up to the good stuff (M1 EP, PUP, Amsoil, etc)

Its probably good oil, but Castrol never certified to the high dexos1 spec, while your Maxlife is. Also, Mobil1 Extended Performance and Annual Protection are dexos1 certified. Its important to me because that means we know it passed a bunch of additional tests on top of SN GF-5. Good choice the Fram Ultra, great filter there.

I drive 45 mins to work twice a week maybe, and live in the city with some short trips mixed in. The reason for the inquiry is I can't seem to get a lot of feedback with Valvoline MaxLife Synthetic going 10k. UOA is a no brainer, but the 2UZ-FE is known for being easy on oil. I have no brand preference honestly, and if the current fill performs well I will likely stick with it. But Castrol EP looks like a great oil IMO. But I know it's gets little attention here

Pretty much any of the big brands' synthetic oil will make it 10k in your Toyota. Use the Fram Ultra, keep the level topped off, and pull a UOA sample at 9-9.5k without changing the oil. Then, since you used an Ultra, just drain and refill the oil and repeat.

45 mins to work twice a week should get the oil up to temp so that's good. Your engine is easy on oil like my Escape... no turbos, no direct injection... 10K is fine. I prefer Valvoline over Castrol since the company is American BUT both Edge and Valvoline synthetic are excellent oils.

He has a Toyota, so Dexos is irrelevant. I can't speak much for Castrol EP but if it was me, I'd use the "real" Castrol synthetic aka German Castrol in either 0W-40 or 0W-30, they're the only synthetics from Castrol to get excited about, in my opinion. I've used them in the past with great results, just harder to find so I'm sticking with Mobil 1 in my Tacoma.
 
Could save a few bucks and use the Fram Tough Guard instead of Ultra, it's rated for 10k miles. I love the Ultra too but can't see wasting it on my puny 8k interval when it can go 20k so I use the TG or Napa Gold.

10K Would not pushing a SN+ "conventional", in this engine, in good working order, under your conditions. Maxlife synthetic should handle this no problem.

Sure it is. See here.
Yes, in the past, it had the obsolete dexos1 Gen1. This is 2018 so we have a few new tests (timing chain wear, GMOD, not just LSPI for DI etc.) on top for the current dexos1 Gen2, which Castrol Exten Perf never got.
Like I said, probably a good oil, yet weird how it never passed or attempted to pass, all the newest performance tests that many other oils like M1 EP & AP have. Maybe timing chains & oxidation don't matter to some people, so use freely.

You're wrong on everything.
1. Its dexos1, not "Dexos".
2. Any GroupIII, IV, and/or V oil is a "real" synthetic.
3. Castrol 0w40/30 has an HTHS that is unnecessarily high for the Toyota spec here.
4. dexos1 is relevant because it has additional performance tests over and above SN GF-5, relevant as far as performance goes.

It could have the new one by now, but now there's no way of checking except seeing a new bottle and seeing if it's got the dexos1 generation 2 style license number.

Of course, to complicate things, when dexos1 originally came out, it was certified dexos1 in Canada before elsewhere.

Well excuse me, sorry for pi**ing in your cheerios, I had no idea the 1 at the end of Dexos was such a big deal! And group 3 is highly refined conventional oil, therefore not a true synthetic. We've been over this before.

Yes we have and Castrol rebates suck to the Max.
 
Very good info! In my application timing wear isn't an issue as the 4.7 has a belt, but oxidation is every bit as important and applies. From memory I believe the Valvoline MaxLife Synthetic meets the new DEXOS1 Gen2 spec
