But this isn't a turbocharged engine, heat and oil temps are much lower.

Many need to learn how to be helpful instead of coming across with attitude and unfriendliness. Attacking me as I try to add to the discussion does not help or do it for me. LSJ has been a big help in helping to educate others but when I see people put down his credentials and act like they know...

That's why I listen to people that know a lot more than I do. LSJ has more experience and expertise that I do and most of use do combined as he's the expert in the field. This is why I listen to what he sees as he can see more, understand it, and over the years see any trends that I might miss.

Well, that's because it's a tool that we have access to. It's a tool, that's it. There are many of you attacking me as I was just trying to help provide more information, so much for that idea.

Then what's the point of any of this? Just use a quality oil and be done with it. LSJ has more knowledge and is an exp[ert in the field, unlike most keyboard warriors.

He has done some videos on filters. I did ask him about oil filters as I've always used Toyota oil filters without ever having an issue. He said that they are fine to use but we didn't talk about them more.

One is looking at wear metals to see if one was lower than the other. On the Pennzoil Ultra Platinum both looked good across the board but wear metals were 20% lower with the 5w-30. I'll continue to follow it to see if this continues.

This is what LSJ said about my 2009 Turbo Corolla too, but he wanted to see what differences we saw with both viscosities. Since the GR Corolla calls for 0w-20, and many of us use 5w-30, it made sense to see how and if the engine preferred one over the other for how I drive it.

As I've said, I never planned on doing it. I've tested both viscosities to see what my engine liked and how it worked with both viscosities. The ow-20 is what is recommended, I wanted to see if 5w-30 or even 0w-30 was a better option. This is where Lake Speed Jr said let's test them both and see...

I didn't say I would be doing that. I did it this past winter as I'm testing both 0w-20 and 5w-30 with Lake Speed Jr. That being said, for people that live with summer heat and much colder winter temps I could see why people do it. In the summer people may drive their cars harder, track it, and...

Not sure why you would say this as it could be viable for people that live in extreme temperature ranges. This being said I pointed out that I would be fine running 5w-30 year round in my region. 😉

I've been reluctant to try anything other than Redline MT-LV in the transmission since I've had such excellent results with it over the past 15 years. I'm very intrigued by the HPL though and for the transfer case and rear diff I'm very interested.

I have concerns running 0w-20 in any turbo car. I to own a GR Corolla and I've been thinking about this since I bought it more than 3 years ago. I have used 5w-30 in the summers with excellent OCI results. I could also run it year round as I don't see winter temps lower than the 20F-30F and in...

I just changed the transmission gear oil with some fresh Redline MT-LV in my GR Corolla and 09 Turbo Corolla. I figure when I run out of it I'll order some HPL. I've got less of the GL-5 75w/85 gear oil for the transfer case and rear diff of my GR Corolla and nothing said that it was a GL-5...

Thanks, that seemed like the logical choice. The GL-5 gear oil for the transfer case and rear diff was less clear to me.
