2011年12月5日 · Are there any conventional oils or blends rated A5/B5? Not that I have seen. Yeah, since A5/B5 is an extended drain spec, it'd be hard for a typical mineral oil to make it. Then again, some mfgs offer 15w-40 oils which meet ACEA A3/B3, and A3/B3 is …

2020年4月1日 · This is just me, but as a Hyundai turbo owner who puts heavy use on his engine, I fully discounted their "recommendation " for a thin A5/B5 oil. I am running Mobil 1 5w-30 ESP which is far superior of an oil with German certs guaranteeing quality in a rough service scenario vs their "mileage only" scenario.

2020年3月10日 · The easiest to find A5/B5 are Pennzoil Platinum and Mobil 1. I selected M1 for the $12/jug rebate. I selected EP over the regular because of the 10k OCI and the turbo, 2-3 bucks per jug more than regular M1 wasn't going to break me. The Mobil 1 high mileage 5w30 also has A5/B5 cert. The Pennzoil Platinum high mileage 5w30 does not have any ACEA ...

2016年9月6日 · ACEA specs are used in Europe by European manufactures, we in US use API(American Petroleum Institute) specs. Most American and Japanese manufactures specify API spec only, not a word about ACEA. American cars perhaps, but every Japanese made car I have bought has had an ACEA spec. But since this is the European and Import motors section.....

2010年12月29日 · The legacy ACEA categories (A3/B4, A5/B5, C2, C3, C4, and C5) still lack LSPI and timing-chain wear protection and provide inferior valvetrain wear protection than API SP/RC (ILSAC GF-6) does. However, the new ACEA categories (A7/B7 and C6) provide LSPI and timing-chain wear protection and provide the same valvetrain wear protection as API SP ...

2010年2月7日 · For most cars, the specification ACEA A5/B5 ILSAC GF-4/5 is recommended. Example of LEXUS, TOYOTA. How the use of oil of the same viscosity, but in the A3/B3/B3/B4 specification, affects wear and engine protection? There is a theory that A5/B5 light running oils cause less high-temperature deposits, lacquers and deposits, especially on the rings.

2024年9月24日 · Was just comparing acea a5/b5 with a3/b4 with the lubrizol relative oil comparison tool (k think it,s called) Even thogh the a3/b4 have a higher HTHS at 3.5 compared to the a5/b5,s 2.9. They where identical on the antiwear probertys.

2013年11月8日 · I have some older Platinum 5W-30/10W-30 5 qt. jugs in my stash. The labels say it meets A5/B5-04. I was at the store last week, and looked over the Platinum bottles they had on the shelf. I noticed it said A1, no more A5/B5. I thought that was interesting. Mobil 1 5W-30/10W-30 says it meets A1/B1 and A5/B5, and Valvoline Synpower says it meets ...

2015年3月20日 · Nope. ACEA A5/B5 and SAE xW-40 are mutually exclusive. According to SAE J300 an xW-40 grade must be >3.5 cP (for x=0, 5 & 10) or >3.7 cP (for x=15, 20 & 25). Originally Posted by 1JZ_E46 A3/B4 and A5/B5 must pass the exact same wear, deposit, oxidation, etc tests. Not quite.

2016年11月23日 · ACEA A5/B5 Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline engines and car & light van diesel engines designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate (HTHS) viscosity of 2.9 to 3.5 mPa.s. These oils are unsuitable for use in some engines.
