Description

Eni i-Sint professional 20W-50 is a synthetic engine oil of a heavier viscosity grade for petrol and diesel engines in cars and commercial vehicles. It is intended for vehicles whose owner's handbook allows a 20W-50.

The oil is rated API SN, SM and CF; the data sheet lists no official vehicle-manufacturer approvals. The maker highlights its anti-wear properties, sludge control and low volatility.

Typical figures: kinematic viscosity 19.3 mm²/s at 100 °C, viscosity index 122, pour point -24 °C, flash point 226 °C, base number 7 mg KOH/g, density 893 kg/m³ and cold-cranking viscosity 9,000 mPa·s at -15 °C.

Application

Petrol and diesel cars and commercial vehicles serviced to the manufacturer's schedule, where a 20W-50 viscosity grade is permitted.

Worth knowing

Alongside petrol API SN, this oil’s list also has the earlier class SM, which no other oil in the i-Sint professional line has; it shares diesel CF with the 10W-30, 10W-40, 5W-30 and 5W-40, while the MS versions lack it. How SM tightened the requirements compared with SL, and which engines API now recommends it for, is explained in the article on the API SM class.

The data sheet gives this oil a viscosity index of 122, whereas the other oils in the line range from 150 to 175. Cold-cranking viscosity for grade 20W was measured at -15 °C, and 9,000 mPa·s stays within the 9,500 mPa·s set by SAE. If the manual pairs 20W-50 with MB 229.1, VW 501.01 or VW 505.00, note that among Eni oils of this viscosity only i-Base 20W-50 claims compliance with all three, though its petrol class is SM without SN and its base number is 10.1 mg KOH/g against 7 mg KOH/g here.
