Description

77 Lubricants Racing Oil 10W-60 is a fully synthetic engine oil based on polyalphaolefins (PAO) for petrol, diesel and LPG car engines, with or without turbocharging, that run under severe thermal and mechanical stress.

The oil is rated API SQ and ACEA A3/B4; it carries no manufacturer approvals.

Typical figures: kinematic viscosity 23.9 mm²/s at 100 °C, viscosity index 187, HTHS viscosity 6.3 mPa·s, NOACK volatility 8.1 %, pour point -54 °C, flash point 238 °C, sulphated ash 1.09 %.

Application

Petrol, diesel and LPG car engines, turbocharged or not, working at high temperatures and under heavy load.

Worth knowing

The pour point in the data sheet is easy to misread: here it is -54 °C against -36 °C for Racing Oil 5W-50, although it is the 5W-50 that has the lower winter grade. The SAE J300 standard does not use this figure; the grade before the W is set by the cold tests, covered in the article on the figures in an oil data sheet. For 10W-60 they are CCS 5,200 mPa·s at -25 °C (the grade limit is 7,000 mPa·s) and MRV 18,330 mPa·s at -30 °C (limit 60,000 mPa·s). For 5W-50 the CCS is 3,890 mPa·s, but at -30 °C, so the two cannot be compared directly.

The stated classes are the same for both cans: API SQ and ACEA A3/B4, with the data sheets saying “exceeds”, meaning above the requirements, and giving no manufacturer codes. So these sheets do not confirm an approval named in the owner’s manual, and the choice between the two oils comes down to the SAE grade the manufacturer specifies. When hot, this oil is noticeably thicker: 23.9 against 18 mm²/s at 100 °C, HTHS 6.3 against 4.2 mPa·s.
