Just got back from 2 weeks in 'Merica, land of the free. I saw a couple of programs and adverts about oil. Anyway, one was about engine sludge and was sponsored by Castrol. On this program, Castrol recommended that oil changes should be carried out "at least every 3000 miles to ensure no sludge build up". A few days later, I saw another program, this time sponsored by Mobil where they declared that "Mobil fully synthetic oil was the only oil to allow oil changes at up to 5000 miles".
Now I know this was advice from programs sponsored by oil manufacturers, but don't these milages seem just a tad short by anyones standards when you consider BMW and VW/AUDI group cars, (and probably others) are boasting of 30000 mile oil changes depending on use. Personally, I would never go that long between oil changes, no matter who advised it!!!
Any thoughts or views?
