Someone at worked mentioned a post that was on Facebook, I think it was one of the various stag ones. Where an owner claimed his triumph stag I had done nearly 300,000 miles. I claimed it had never broke down. Whether that was just during his ownership, which she didn’t mention how long that was or if you had the car from new.
Then another owner piped up and said his had done nearly the same. once again extremely reliable and it had never suffered from any issues.
They may have been telling the truth, a little bit, but from what I can see there’s a few people who weren’t 100% convinced that a stag could do this sort of mileage without going wrong.
I was just interested to see what the total mileage of people Stag’s where, and how far they thought their car would go in between engine rebuilt or gearbox rebuild. From what I can gather a good quality set of timing chains will last about 20,000 miles. engines would roughly need rebuilding within 40,000 miles. This is why I found it a bit almost unbelievable that someone triumph engine stag had done 300,000 miles without needing any remedial work, or do you think this may be achievable. |

I've seen chains that have done in excess of 30,000 miles and all was still good. I think 40,000 miles for a rebuild is a bit on the low side personally I would say well north of 80,000 would be a more realistic figure. The secret, I believe is oil and filter changes every 3.000 miles.
I knew someone with a Volvo 740 which had done nearly 300,000 with no work other than serving, but I would question a Stag owner making that claim.

I had a Volvo 760 Turbo, very fast car. The more I pampered it, the more it let me down so for 80,000miles I did nothing but fill it with petrol, the spark plugs must have welded to the heads, dont know, never changed them, never let me down once! Until an electronic part failed and it was written off.

I think that the secret of reliable high mileage is lots of long journeys. Most wear occurs when starting from cold.
Many years ago I was talking to an Australian Triumph saloon specialist who was over here looking for engines gearboxes and back axles.
Over there, due to lack of rust and the distances to be covered, the big saloons would do huge mileages. He reckoned that 250,000 miles was common before a top end overhaul, and bottom ends would generally do 400,000 miles
I reckon this is about 4 times they would generally do over here.
A friend of my dads did huge mileages for work back in the 80s, generally about 70,000 miles per year. He had an MGB that did 240,000 before it became a bit smokey. He replaced it with a Rover SD1 3.5 that reached 220,000 miles before one rocker arm lost one of the steel cups in its alloy rocker arms, that was in about 3 years, so it had probably done over 300000 when he unfortunately died of a heart attack at the age of 46.
My Nephew who lives in the USA in North Carolina has done close on 100,000 miles in 12 months in his Toyota 4x4. His girlfriend live an 8 hour drive away as well as his work mileage. Just as well fuel is cheap over there at 20mpg!
Certainly things like timing chain sprockets are made of monkey metal compared to original items. Also I have come across many blocks fitted with liners from the factory. I have one that has liners on one side and the original bores on the other. There is significantly more wear on the liners than on the original bores, must be softer metal.
I reckon that 300,000 is not beyond the realms of possibility. Bear in mind though, if you were doing high mileage in your company Stag, you would take it in for a routine service and things like timing chains would just be done as part of the regular scheduled service and the invoice would be paid and the work forgotten about
