dear members, first let me thank you, for being great knowledgeable helpers. ok, remember my frustrating search for oil, for my pajero? well, here's my experience so far: from zero knowledge, to 30\40% knowledge.(i hope so ) i decided to go for the best oil i could find. 5w30 valvoline synpower XL III c3. spec: ACEA C3-10 Suitable for use in engines where ACEA A3/B4 is recommended Meets all engine protection requirements of ACEA C2 BMW Longlife-04 MB-229.51 Porsche C30 Approved under VW Standard 504.00 / 507.00 previous engine oil was: champion 5w30 c3. spec: API: SN/CF MB: Approval 229.51 VW: Approval 502 00 VW: Approval 505 00 VW: Approval 505 01 ACEA: C2* ACEA: C3-10 BMW: Approval LONGLIFE-04 GM: Approval dexos 2 the HSTH on valvoline is >3.5 don't know what champion oil HTHS. from what i can see, the valvoline edge is b4 support. so it's must be better right? the problem is: with the champion oil, when i "floored" the paddle, my rear wheels would whirl on the spot. (when the rear wheels turns freely, you would see an icon say: "car is slipping", and you can feel the car slides) after the filling the new valvoline oil+genuine oil filter, my car doesn't do that anymore. kinda bummer, but not a deal breaker. also,i wanted to ask you, what's better oil: 5w30 b3\b4 c3 or 5w30 a5\b5 c3 or 5w30 e1 e2 e3(dont remember exactly, but i remember saw c3 oil with couple of E standards) i wish i could have caltex 5w30 oil, the best oil all around by far, but i don't think i can find it for sale. :\ sorry for the long post, but i wanted to give you detail picture. thank you, and all the best.
