TITAN CARGO SL SAE 5W-30 is a top performance, extreme fuel economy oil for a variety of commercial vehicle and off highway diesel engines with optimum cold starting and lower oil consumption. TITAN CARGO SL SAE 5W-30 was developed to optimise the reliability and cost effectiveness of vehicles. The fully-synthetic TITAN CARGO SL SAE 5W/30 provides continuous reduction in fuel consumption. This is ensured by reduced friction, rapid oil circulation and extreme wear protection. TITAN CARGO SL SAE 5W-30 demonstrates special cost-effectiveness with extended engine oil change intervals of up to 160,000 km. The special aging stability and the excellent wear protection lead to optimum reliability.
OK, so I would not use it. It's made for a different application, off road diesel engines with OCI up to 160,000KM / 100,000 miles.
A typical light duty diesel engine oil would be a C3 oil with a TBN of about 7 with an OCI of maybe 10,000 to 20,000 miles
I don't think it's worth the risk, different oil, different application.
