Triuphs after 70 were stuck with no ' Friction modified ' oils due to common supply , Engine and clutch .
Oweva , thats NOT the case here .
Having seen a 265 Valiant subjected to a few decades of hammereing , W.F.O operation , on a 680 c.f.m. 4 barrel carb .
on teardown , bearings shafts pistons and bores were within service specifications . Regular oil changes , on a oil burner .
(was when he got it , but considered the oil pulled down valve guides on stat up lubed the cylinders.
procedure was , Oil & filter , 4 litres oil , one litre MOREYS Heavy Duty Oil Stabilizor , burn a second 4 litres , and repeat .
( no oddometer ).
The MOREYS is pretty good stuff . Tecnically the additives in oil are consumed , hence the typical British ' 500 miles per pint
keeping fresh additives supplyed . (specifically Jaguar , Mk 2 etc )2.000 mile oil change interval .
Later people thought engines shouldnt consume oil. ( and fitted valve guide seals , etc .
) and increased quality alledged
or oils allowed longer service intervals . So they say .
Food for faut . :lol: This gook and S.T.P. ( specially treated petrolium , no less ) are alledged to adhere to components .
Older dungers where theyre akll coked up , transfer the gook to the new oil , gets black quickly . SOOT .
Thrashing engine ( if all adjustments and tolerances are with spec ) tends to keep it clean . The Excusive Breatheran
were the local Cortina ohc 1600 / 2000 Engine Overhaulers in the mid north .One was the spare bloke at the Ford Agent .
There Transits ran 2000 o.h.c. , in the cars , typically the 1600s were in beter order for the milage , as they had to be
rowed along . Worst were old geezers 2000s , due to them being loath to change gear and Lugging the Engine .
So we were reliably informed .
Found a few old wideline featherbeds out that way , late 70's Almost lost one to a milk tanker one sunday afternoon
through the S bends , holding on to it on the back of a pre unit 650 , Farmer Brown steering . Not unusual for those parts .
