    Raybestos E3 rotors rusting earlier than expected

    I recently replaced the front rotors on my Rav4 hybrid with Centric premium coated rotors on the driver side and Raybestos E3 on the passenger side. I did not intentionally mean to do this at the time I replaced the brakes but the good news is I get to compare the anti-corrosion performance on...

    Best HM oil for extended OCI?

    Thanks for the helpful feedback everyone. The 2.4 liter engine I'll use this in leaks a little oil past the oil pan gasket but not enough to drip on the ground. As soon as it starts dripping on the driveway I'll replace the gasket but I'm hoping to get away without having to do so for as long as...

    Best HM oil for extended OCI?

    Hi, I was wondering which HM oil would be preferable for extended drains? I was thinking I could safely do once a year OCI if I put no more than 10k per year on my 02'camry with about 100k miles on the odo. I am leaning towards M1 HM but was also wondering about Valvoline ML Syn as I've seen it...

    mobil 1 10w-30 hm vs maxlife 10w-30 full synth?

    I noticed the spec for M1 HM oil still specs under SL rather than the newer SN rating. Not sure if this makes a difference. The Valvoline site is down for maintenance but I saw reference to it's HM oil rated SN.

    Oil known for its effective cleaning ability?

    hmmm, thanks for the input everyone. I didn't know Penz had a newer oil than their platinum product. It does seem like Penz is putting a lot of emphasis on "self cleaning" with all their oil, especially PU.

    Oil known for its effective cleaning ability?

    Hi all, I recently picked up a used 02'Camry with the 2AZ-FE 4cly engine. It has about 96k miles on it and runs quite well with very minimal oil seepage around the oil pan gasket. I recently put in Pennz HM but I was contemplating using an oil known for its cleaning abilities at the next OCI. I...

    Spare Tire impact on differential question

    Ha, I just realized I should have measured the difference in tire size between spare and full size after taking into consideration compression of the sidewall once installed on the vehicle. The donut spare has a smaller sidewall height and is pumped up to 60psi so the sidewall will not compress...

    Spare Tire impact on differential question

    Thanks for the comments everyone. I really appreciate the education from it. It's strange that Subaru warns that all four tires should be within 1/4" circumference and yet they equip their vehicles with an off-sized spare tire. Subaru does offer a slightly larger diameter spare tire for a...

    Spare Tire impact on differential question

    Thanks for the input fellas. Basically the manual gives general precautions such as keeping speeds below 50mph and to only use the spare tire on the rear. I've seen these same precautions on other non-AWD vehicles so I'm not sure if they are specific to the concern for drivetrain wear but I can...

    Spare Tire impact on differential question

    Hi all, I was hoping some of you experts out there can shed some light on a concern I've had. Here's my scenerio: I have Subaru equipped with a manual transmission with full time AWD. The front and rear differentials are open while the center differential is viscous coupling (standard Subaru...

    Leaky purolator filter

    I've used the new gold Purolator filter on my 2009 WRX twice and both times they never leaked a drop. I'd check to see if any of the textured grip material was poorly applied near the gasket and is preventing the filter from fully seating. I've noticed recently the purolator filter lookup...

    The knock you have, does it sound like the infamous subaru rod knock that is on youtube? If so I'd call SOA and tell them that your dealer would rather have you wait until the car broke down in the middle of the road before even investigating and repairing the vehicle. I'd go to another...

    PP 5w-30 09 WRX

    Ed, do you happen to remember the part number of the subaru filter your checked? I'm wondering if perhaps only select subaru filters have a Si valve. I'd gotta say I'd be very suprised if Subaru would publish false information without checking the facts.

    ha, yeah I thought the same thing when I got this in the mail. I don't think it's going to do much to sway opinions but it's nice to know Subaru is trying.

    PP 5w-30 09 WRX

    Oh no, I'm sorry to hear about your rod knock issue. Sounds like you are experiencing what I was fearing with my car just after purchasing it. I think you could take it is now regardless of what filter is on it considering the amount of documented cases of rod knock that have been seen on the 09...

    PP 5w-30 09 WRX

    huh, yea I pondered this for a long time. I've decided that while Fram is indeed produced by Honeywell, that doesn't mean I am using an off the shelf Fram by using the OEM filter. Until I see a documented failure of a Honeywell Subaru filter I'm not going to worry about it. The PureOne filters...

    It's 3,750 miles. I like to live dangerously Actually, I can't get myself to change the oil every 3,750 miles. I'm not implying I know more than Subaru engineers but I just feel it's a waste of resources, energy, and time to change it out so early if using a high quality synthetic oil at the...

    PP 5w-30 09 WRX

    Yeah, I'm pretty happy with the wear numbers I'm seeing. I gotta say I was pretty scared to see the large number of people who were having their engines replaced within months after their purchase. I was looking for signs of Silver in the UOA which appears to be the telltale sign of inevitable...

    Ok, lets try this: Blackstone Comments: Aluminum, iron, copper, and silicon all improved nicely in the second sample form the 2.5L in your Subaru. At this point, silicon is the only left-over from when the engine was new, though we fully expect it will decrease again next time and when it gets...
