Suzuki- oil viscosity thoughts after dealer switch to 0W-20

[Kccv23highliftcam]

Hmm interesting one.

Dealers now switching to 0W-20 as service fill.

Is this because of the newer smaller turbo charged engines?

Seems a bit odd for a 2009 80,000 miles swift vvt to be suddenly moved onto 0w-20 after decades of 5w/10w-30/40.

Not sure of who is their oil supplier now? does anyone know who it it to compare specs??

cheers

I'd be telling them to stick it up their arse and replace it with the correct oil.
Check your handbook first though.

I suspect they're getting a good deal on it, but if it's the wrong spec for the car it's a risky strategy.

Suzuki engine oil supplier is now Motul. this change-over happened only very recently previous supplier was castrol.....


0w-20 Eco-lite PETROL ENGINES ONLY

TYPE OF USE
"Fuel economy" engine oil specially designed for recent cars, powered with gasoline engines,
designed to use oil with low friction, very low HTHS viscosity (= 2.60 mPa.s) and "Mid SAPS" reduced
content of suphated ash, phosphorus (0.06 = x = 0.08%) and sulphur (= 0.5%).
Catalytic converter friendly.
These oils may be unsuitable for use in some engines. Refer to the owner manual or handbook if in
doubt.
PERFORMANCE
STANDARDS API SM / CF
RECOMMENDATIONS Honda Europe gasoline engines, Mazda gasoline engines,
Subaru SOHC (single overhead camshaft) engines
Back compatibility of new API SM standard over API SL requirements and former API standards.
API SM lubricants provide outstanding oxidation resistance, better anti deposits protection, better
engine cleanliness, anti wear protection and enhanced performance at cold temperature during all oil
life span.
0W-20 grade minimise oil hydrodynamic friction, allows fuel economy specially when oil is cold.
Improves oil flow at start up, faster oil pressure build up, faster rev raisings and reach operating
temperature faster.
Environment friendly, those oils allow fuel consumption reduction and then minimise green
house gases emissions.
RECOMMENDATION
Drain interval : according to manufacturers’ recommendations and tune to your own use.
Can be mixed with synthetic or mineral oils.
PROPERTIES
Viscosity grade SAE J 300 0W-20
Density at 20°C (68°F) ASTM D1298 0,838
Viscosity at 100°C (212°F) ASTM D445 8,8 mm²/s
Viscosity at 40°C (104°F) ASTM D445 48,6 mm²/s
Viscosity index ASTM D2270 162
Pour point ASTM D97 <-50°C / <-58°F
Flash point ASTM D92 238°C / 460°F

Hmm..

Its in the handbook as to which oils you can use but the main reason they would use a 0w20 is that engine tolerances are far tighter than they were 20-30 years ago so there is no need to use a thicker oil if they can use a thinner one with less friction, moves the heat better and gives better protection and economy.
