I bought a couple of bottles of this today for my upcoming oil change, seemed like a decent price when comparing to other suppliers

it's what the volvo/bosch specialist place put in it when they did a service and belt change for me
that said annual oil changes for me work out to about 5-6000 miles so I'm not overly concerned about it lasting forever as long as it's nice clean oil and not burning any (level gone down about 10mm on stick in 14 months of use)
