Of course, it may well not NEED an A3 spec oil, but I'm throwing it out there anyway. We all know the M1 0w-40 is an approved lube and a great value.
My 2007 V70 & V70R manual states the following:
Engine Oil specifications: "Engine oil must meet the minimum ILSAC specification of GF-3, API SL and A1/B1." Also: "Synthetic oils meeting SAE 0W-30 and 0W-40 and complying with oil quality requirements are recommended for driving in areas of sustained temperature extremes (hot or cold), when pulling a trailer over long distances, and for prolonged driving in mountainous areas." There is no mention of meeting an ACEA A3 spec or HTHSv of 3.5cp or greater. PC Duron 0W30 has an HTHSv spec of 3.3cp and an API SM rating.
Is it a mistake to run PC Duron 0W30?
Hi Sam,
I'm surprised you can get PC oils in Connecticut and $3.12/qt is as super price.
Yes the HDEO Duron 0W-30 is an good choice for your Volvo. PC oil are a bit shear prone but that should be a non issue since Duron is a heavier than necessary oil to start with. (See the following UOA compared to a TGMO/M1 0W-40 blend):

For the OP, since a light 30 grade oil is what's spec'd by Volvo I wouldn't be using GC or M1 0W-40. Any 5W-30 syn' would be preferable but if you are going to be starting the car unaided at temp's down around -30F, M1 AFE would be a good choice.
Everything I have read says GC is perfect for Volvo engine as they like a heavy 30wt oil. Has this changed?
