I would change oil and filter every three years - about every 7000 miles. My TR7 also does few miles a year. I have changed the oil and filter six times in the past 30yrs after never more than 6,000 miles. The engine is nearly 40yrs old, has done over 70,000 miles, works very well and requires no top-up between changes. I see no reason why your engine should not last this long as well.

The annual oil change whatever the mileage is a massive multi-million pound scam imposed by the garage trade and their associates upon tens of thousands of pensioners. It might have made slight sense sixty years ago when ill fitting pistons allowed contaminating blow-by of incompletely burnt fuel and crankcase breathers were open to air allowing ingress of moisture and degrading micro-organisms, but nowadays with sealed well built engines and modern oils it is just utter nonsense - and HJ should be ashamed of perpetuating it.

As you are changing it yourself (i assume, as you did it first time), costs are minimal, so i would change it every year.

Just for you JohnF, i change mine twice a year, even with the sump holding 7.5 litres an oil change costs me about £25 including the filter...oh and i buy oil and filters in bulk :-)

Thanks all, just wanted to know what you thought. Personally I would do it yearly anyway regardless. It's a cracking car and well looked after so would be false economy not to change the oil I think. Low stop start miles, not getting a chance to warm up most of the time.......Yes I'll stick to yearly.

Thanks everyone for your input

Avant, I have just read this with dismay. I never resort to personal abuse. Please either confirm this or display the debate.
