They generally are very, very good, one production run of dodgy petrol engines given the millions they have produced over the years plus diesels are new to Toyota, looking at their record over the decades you can't really beat Toyota engine durability - Toyota are standing by their customers by changing engines out of warranty - I can't see VW doing the same for the thousands of blown engines due to premature cambelt tensioner failure or to oil pump drive failure... Yes there have been some great VAG group engines but mechanical greatness is normal for Toyota.

Just been in a toyota avenisis diesel taxi to pick up my car the driver said it was on its third new engine and this was using oil they got afew of these to replace their aging Mercedes e class a special deal from Toyota everyone has blown its engine so he said.The next contract they are going back to DB.I thought Toyota were supposed to be good motors its appears not.

Obviously not heard of MB's diesel problems then ?

I dont think so the oil consumption has been 700 miles per litre over the part five years with no change from winter, spring, summer or autum. So I still believe this is due to the high octane flushing the scraper ring grooves. On the Toyota Owner Forum there is a reply from a Reault owner with the same problem, which Renault try to cure by double flushing the effected engines on each oil chnge.

If you read my original post carefully you will see that I mention that its probably the detergent that is flushing the scrapers ring grooves not the high octane. There is some addative in the high octane that is reducing the oil consumption.
