    Default What oil weight?

    2006 xc70- 100K...been using Mobil One...Its now approaching summer in NY....what viscosity M-1 do I use? The local stores have only 5-30, 10-30. There is also this HIGH Milage M-1. I want this machine to last...it's not using any oil at this point...changing oil/filter every 3-5K.

    Mobil One European Car Formula 0W-40 is ideal for Northeast US.

    Suitable for our cars year round in virtually all climates.

    Used by many of us here.

    Usually available at Walmart.

    Also can be purchased through NAPA, O'Reilly, Pep Boys, Advance Auto Parts, etc., though you may have to order it if local store doesn't keep it in stock.

    I was thinking of making the switch now that it’s getting warmer. Is there anything to watch out for when switching from the 5w-30 the first time or is it just a standard oil change with a different weight?

    No difference in procedure. Nothing to watch out for. Just change normally.

    Use whatever “weight” you like (seriously) but make certain that it’s designed for long drain interval. More important than viscosity is the additive package that supports long drain intervals. Like ACEA A3/B4, MB 229.5, BMW LL-01/04.

    Talked about this a while ago, here: https://www.volvoxc.com/forums/forum...7-XC70-(V70XC)

    I’ve used, with oil analysis to back it up, Mobil 1 0W40, Pennzoil Euro 5W30 and 5W40, AMSOIL signature series 0W30, Castrol 0W40. They all meet long drain specs.
