IMHO the oil I use for my fleet meets API CG4/SJ and is further rated to MB228.3 long drain SHPD, is wasted at the Toyota recomendation of 4500 mile drain in a 1HD-FTE engine. The oil will easily last double your recomendation. In the event I am using a synthetic Fuchs Titan Cargo 1040 oil which is a 60,000 mile type oil and to Hell with your warranty. If the engine fails then both oil and filter will be sent for analysis and you will have to prove that the failiure was due to inappropriate servicing. With this oil the regime is to change the filter every 5000 miles and the oil at 10,000. > > If you decide to use synthetic oil for the engine, it is best not to switch > until the first scheduled oil change.

I wouldn't trust most main dealers to repair a wheelbarrow. Huw
