Club Triumph

Daisy is a 1974 (registered 1/1/75) Toledo 1300 4 door. Just coming up to 60,000 miles which I believe to be genuine.

Runs beautifully. I was on the M25 earlier cruising effortlessly at just on 70 with no rattles or nasty noises bar a hiss from the quarterlight.

I have just realised that I don't use her enough. Recent issues with my Alfa Romeo (and, glutton for punishment that I am, I'm acquiring a second one this weekend), working for a living etc. meant that Daisy stood idle for over a month and needed to be jump-started. She's only doing about 1500 mile a year at present.

So, I plan to use her at least once a week, probably on my daily 25 mile each way commute which does include afore-mentioned M25 plus a fair stretch of A41 dual carriageway.

I have been using just standard unleaded fuel but I am wondering if the new usage make use of a lead substitute or upper cylinder lubricant worthwhile?

The odd dose of Millers VSP can't do any harm (except the wallet) - if you don't thrash it I wouldn't stress too much

If you really do want to put an additive in just use an higher grade fuel like Shell optimax or whatever they are calling it now.
it will take about 30k miles for you to see any effect caused by not using lead additive.
Whatever you decide DO NOT  buy one of those inline or intank gizmos as they are just snake oil crap.

A lot of people say use it on unleaded, it will run for a good 30K with no issues, then when the valves do start to recede or you get a burnt valve just change to an unleaded head then. Not worth putting a new head on now when there's going to be nothing wrong with the current one for the next 30K miles.

Thanks for the advice.

I think I'll leave it well alone, just maybe splashing out for the super Shell petrol to give Daisy a bit of a treat.

...If it's the same engine as the 1300 Dolomite, the handbook recommends 97RON which these days will be 'super' unleaded. I've got that engine in my 1200 Herald conv. & when I initially started running it on 'ordinary' she used to pink...now runs much better on the liquid-gold stuff. I used to put a 'sniff' of Millers in but my local garage hasn't had any in stock for a long time & there don't seem to be any ill effects.....
