I'd agree, as a young lad my dad made me take my first car to a guy up the road who looked after everyone's car, the general rule of thumb was 4 oil changes every year, NEVER EVER increase revs until oil and water needle was up to operating temp,
And every time he filled it back up with clean oil he said the same thing 'if that engine could talk it would be thanking you now"
I later found out that he was a rubbish ventriloquist! He had an Oil burning heater for his home and he'd cleverly utilised the pit in his garage for extracting a means to heat his home whilst getting paid for servicing work, but I still change my oil every season and think the same thing every time !
