My list was mostly the manual recommendations but modified it in the few places like OCI, transmission, diff, and added some other things like PCV valve where it seemed appropriate. Agree coolant at 137k seems like one additional place this should maybe be shortened.

Good point. Guess it depends. Pads (and tires) on any of my cars probably don’t last much more than 30k. Roads are hilly and windy where I live.

Thanks. I understand this is best, but I feel like if I do a pretty good bleed and fill every caliper pad replacement, I’m probably better than the 99% vehicles out there. Not true?

I was bored today, and thought I would put together a Subaru maintenance strategy using Subaru’s guide and info learned here. Using Top Tier gas and only BITOG endorsed fluids… Subaru Maintenance Best Practices: Initial Break In Period - 1,000 mile and 3,000 mile oil changes - 5,000...

So I ended up going with Motul Gear 300. So far, negligible difference in feel at startup and a little less notchy when it’s up to temp. Pretty happy, but it’s summer. Curious how it will feel in winter. Would love to hear any MT experience for the WRX VB in winter on Motul Gear. 300 vs HPL...

I agree, great analogy. I’m a big believer in Valvoline Restore and Protect too, but to continue the analogy… it would be like if we have only had people living on the pescatarian diet for a few years, and we still don’t know how this diet compares long term to other diets. And before...

Thanks. I wasn’t really trying to debate extended OCIs directly. I am trying to understand if the wear rate accelerates the more miles you run on an oil because it builds with <15 micron particles not filtered out.

Please help me understand. I’ve heard multiple times that a lot wear is from <15 micron particle size, which is mostly not caught by oil filters. Yet it seems like many people are confident in going extended oil change intervals just knowing the oil stays in grade and fuel dilution. Does the...

So I’ve been researching Subaru WRX MT options, and get a little overwhelmed with things like yellow metal risks for GL-5 in MTs. I don’t care about fuel economy or cost much. I do care about wear and good shift quality in all climates. I and am debating between: 1. Just paying a service...

Would Valvoline 4-Stroke ATV/UTV10W-40 be a good choice?

15k miles still seems pretty reasonable then, and has to be well better than the average person.

Thanks! It looks like Amsoil actually makes a 75W-85 grade too, which is a little closer. Which would you recommend? I don’t care about fuel efficiency, I just don’t want to change shift quality feel.

Motor Oil Geek is recommending transmission and diff changes at first 5,000 miles. How much does this community buy-in to the need for this? (I was aiming to change these at my manual’s severe service recommended of 15,000 miles, but now wondering if I should sooner).

My 23’ WRX manual says to use Subaru Extra MT but 75W-90 is ok, but “4: You may use this type of manual transmission oil. However, using this type of oil will detract from driveability and fuel efficiency.” Does a good 90 weight such as Amsoil Severe Gear 75W-90 make the shifting feel worse?

Thanks. I am new to posting and will keep reading. I am also a big fan of Valvoline Restore and Protect and use it exclusively in my older cars. I would be interested in what you think would be the drawback to switching to Mobil 1 ESP after using Valvoline Restore and Protect for enough...
