    Two Questions

    What is the difference between Mobil 1 10W30 High Mileage and regular Mobil 1 10W30?

    Also, If you hold the brake down and are on a hill, is it true that holding the clutch out to where it grabs wears it out (clutch)?....or is bad at all?

    Since my clutch is new I hold out the clutch to wear it grabs, so that i dont give it too much gas and so the car wont roll back, and then i give it gas and ease off the clutch.

    I appreciate any help

    It seems the additive package is better for the HM oil. The HM variant is an ACEA A3 oil, whereas the "plain Jane" is only A1; also the HM variant has higher cSt at both 40 deg. and 100 deg., and also has a higher flash point and a lower pour point. Given the same price I'd opt for the high mileage variant. I have not looked at the respective MSDS files to see what might be in there, but they are all available as dictated by law. See Mobil1.com for files, info, etc.

    EDIT: I'd not hesitate to use the 0W-40 Euro or 5W-40 "turbodiesel" year round anywhere in the continental US. For example, I do use either of those depending on what's cheapest and closest to me on the shelf, and will continue to do so.

    Also, If you hold the brake down and are on a hill, is it true that holding the clutch out to where it grabs wears it out (clutch)?
    Yes.

    taking SDGR's advice i have been running 0w-40 for the last year, i replace up to half a quart at 1500 miles replace every 3k and the car runs great.

    I tend to use more of the 0W-40 than the 5W-40 also. Your rate of use probably mirrors mine. I have an older car and don't bother replacing the oil before 5,000 miles (for a newer motor I'd follow Subaru's TSB to the letter and in any case I keep all receipts).

    I'm at the century too. I'm looking for someone to do the timing belt because for months now I've been dreading it, thinking of my back, my knuckles, and other such un-manly thoughts, and it's occurred to me that if I don't want to do it, I don't have to - I can hire a shop. Hah! My back feels better already just at the thought.

    I've gone through the RE92s, a set of Avons, and now I'm 2/3rds done with a set of F1 GS-D3s that I love.

    Not even for like 3 seconds?

    Because I know it says not to hold the car like that while you are waiting at a light on a hill..

    It's unavoidable to ride it sometimes but in general I'd recommend you use the hand brake instead. It wears the clutch less and is also IMO safer.
