2020年3月22日 · You can also run a high-HTHS oil (HTHS ⥠3.5 cP), but make sure it's mid-SAPS, meaning ACEA C3 or GM dexos2; otherwise, full-SAPS oils like ACEA A3/B4 will increase the rate of the accumulation of the intake-valve deposits in your GDI/TGDI engine.

2015年10月6日 · Alas, if you really want an oil meeting ACEA A5 spec, then Pennzoil Platinum 5w-30 meets it. Castrol Edge 5w-30 as well. Welcome to BITOG! Valvoline Synpower 5w-30 does not meet A5/B5. No mention of ACEA on recent Synpower bottles. But the Platinum is a good choice, since it's on sale AND a rebate as well. $5.69 at Napa, plus a $2 rebate per quart.

2023年3月20日 · For one thing ACEA Sequences are not approvals, and are self-certified. So even if there was a list it would only contain oils that were reported to the ACEA and it wouldn’t be complete. Just go to Walmart and find something on the shelf that has the Sequence you want. Or buy it online from AMZ or Walmart. Brand is going to be nearly irrelevant.

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.

2011年12月5日 · It came from ACEA's description of the spec: Quote: A5/B5 Stable, stay-in-grade oil intended or 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 ...

2009年2月14日 · A5/B5: Stable, stay-in-grade engine oil intended for use at extended drain intervals in passenger car and light duty van gasoline and diesel engines designed to be capable of using low viscosity oils with high temperature high shear (HTHS) viscosity of 2.9 to 3.5 mPa s.

2011年12月27日 · If the ACEA spec for HT/HS is 2.9 min. - how can Amsoil (ALM) 5-20 meet A5/B5 with a 2.8 HT/HS? I believe Amsoil should comply with the actual ACEA testing criteria if they are claiming it in their specs. Please comment Amsoil reps, FWIW-- Oldtommy This has been brought up several times. So I emailed Amsoil - and they said they would change the ...

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.

2010年12月29日 · The reason why the legacy ACEA categories (A3/B4, A5/B5, C2, C3, C4, and C5) provide less valvetrain-wear protection than API SP/RC does and provide no timing-chain wear protection is because half (50%) of the existing legacy ACEA oils failed to pass the valvetrain wear test at the API-SP/RC limits and another, different half (50%) failed to ...

2019年6月10日 · Yeah, GM6094 is an outdated spec, if I'm not mistaken. Likely retired when Dexos was introduced. My guess is any 5w-30 oil would be fine, if you don't run extended oil change intervals. And if you do, I would think any Dexos1 gen2 approved oil would work fine, as would ACEA A5/B5 oil.
