This is why oils like 0w20/30/40 both have good VI and are composed of real synthetic base stocks (because they have to be to meet the 0w20/30/40 numbers).Ĭrap I thought more reading would clear this up and I would just move to X-clean EFE.now I am more conflicted than ever. I definitely do much less spirited driving and less longer drives in the winter.well with the exception of the occasional hoon in fresh snow (ice covered by 6 inches of snow last weekend baby)Īccording to my recent reading, the better low temp viscosity and higher VI usually indicate real synthetic (maybe better) base stocks in comparison to some (most) 5w30 "Synthetics" that are ultra refined dino-oil-stocks.
I wonder if my car ever really reaches normal operating temps for the oil (I don't have an oil temp guage) during these drives.īut I am sacrificing normal op temp viscosity to stay with the Sustina.and I think (THINK-who really knows) we can all agree that the EJ257 could use a thicker oil at operating temp. In the winter most of my driving is cold start (in garage) - 5.5 miles - cold start (in parking lot at work) - 5.5 miles home. So now I wonder if by going to EFE I am sacrificing startup/cold operating protection. one that is closer to the desired operating temp value) will protect better at cold temps than the lower VI oil because it flows better (more like normal) through the passages. It means that an oil with a better/lower 40C viscosity (i.e. The desired 30 wt (the 30 in 5w30) viscosity at operating temp is between 9.3 and 12.5.Ī higher viscosity index (VI) is better because it means that at low temps the oil is closer to the desired running viscosity. X-clean EFE 5w30 40C viscosity = 70.1 100C viscosity = 12.1 viscosity index = 169 HTHS = 3.5 I am currently using (but considering going away from to X-clean EFE)Įneos Sustina 5w30 40C viscosity = 51.5 100C viscosity = 10.3 viscosity index = 194 HTHS = 3.1 Viscosity that is ~25% higher than other oils with an HTHS ~3.0-3.1. Do not mix with lubricants not ACEA C3 compliant.One thing that I have noticed is that while the X-clean EFE is a HTHS 3.5 oil it also has a cold This specification applies to all PORSCHE engines, except Cayenne V6 and Diesel versions (for these specific engines, use an approved Porsche C30 lubricant such as MOTUL 8100 X-clean+ 5W-30). They should all be more shear stable than a GF5 oil and the difference in the three is likely anti-wear additive levels. acea standards: acea c3 api standards: api service sn oem approvals: bmw ll-04, mercedes-benz mb-approval 229.52, mercedes-benz mb-approval 226.5, porsche c40, renault rn0710 - rn0700, vw 511 00 oem performances: fiat 9.55535-s2, fiat 9.55535-t2, general motors gm dexos2 oem recommendations: kia, hyundai, honda, mitsubishi, nissan, suzuki. The Porsche A40 standard requires extreme high shear resistance from the lubricant. If Motul is only producing 8100 X-Clean EFE and 8100 X-Clean FE which would provide better protection without shearing to a 20W before 3,000 mile changes X-Clean+ is also one of the new ones along with EFE and FE. The specification MB 229.51 applies to some MERCEDES Gasoline engines, and to all MERCEDES Diesel engines, with or without DPF. The MB 229.51 requires a reduced content of SAPS in order to be compatible with MERCEDES exhaust gas after treatment systems. Also, GM-OPEL dexos2 TM fully supersedes and replaces the previous GM specifications: GM-LL-A-025 (Gasoline) and GM-LL-B-025 (Diesel). high HTHS (> 3.5 mPa.s) viscosity and 'Mid SAPS' with reduced content of Sulfated Ash (0. GM-OPEL dexos2 TM standard is suitable for the whole range of GM-OPEL Diesel engines (including DPF versions) and most of Gasoline engines from Model Year 2010. For vehicles that are Euro 4, 5 or 6 emission regulation compliant and require an ACEA C3 engine oil i.e. The FORD WSS M2C 917A standard is required for FORD Galaxy 1.9L TDI until MY2006 and for FORD Ka from MY2008. Outside those countries, a BMW LL-01 lubricant such as MOTUL 8100 X-cess 5W-40 is required. ATTENTION: BMW LL-04 product can be used for gasoline engines only in European Union countries, Switzerland, Norway and Liechtenstein. It covers all BMW engines from 2004 and also all BMW engines before 2004 as BMW LL-04 covers all the previous BMW specifications such as BMW LL-98 and BMW LL-01.
The BMW Long Life-04 specification imposes severe constraints to the lubricant particularly due to Valvetronic and after treatment systems compatibility.
Numerous OEMs such as KIA / HYUNDAI, HONDA, MITSUBISHI, NISSAN, recommend an ACEA C3 lubricant for most of their vehicles especially Diesels with DPF. ACEA C3 lubricants achieve extended drain intervals managed by vehicles on-board computer. PERFORMANCES: The ACEA C3 standard requests from the lubricant significant oil film resistance and low emission performance for powerful engines.
