As I am restoring my MK3 S engine to original standard specifications, is there a need to put oil thermostat on 13 row oil cooler or not?
Or can I put standard oil cooler setup without thermostat but with cover on oil cooler?
Car will be used as weekend drive and maybe for couple of international meetings during summer.
Race it, brake it, fix it, repeat ...
This is only my opinion as an engineer and not as a lubrication engineer/chemist..... I have read all of the recent articles with great interest and agree with it - but only so far - ! Like mine, your engine is to be bog standard (that's one of those technical engineering terms for something that's bog standard!) and if you ain't doing anything out of the ordinary, such as thrashing seven bells out of it or slogging it to death pulling a horse box, then with modern lubricants, then just leave it bog standard. That's my K.I.S.S. answer. Others might have different ideas. But for the likes of you and me and our bog standard cars, then if it ain't broke then there's no need to fix it!
Love to hear other comments.......
Dont forget that the oil does the gearbox as well as the engine, so it always gets hot. I run an oil cooler and if it gets cold I put on the S/T cover. On another note , I change the oil every 1000 miles and I use semi-synthetic oil.
HI, I have recently had the same issue. oil has advanced so much since the 1970's. I would recommend using MILLERS oil for your Cooper. @Â£35 a go its good value.
I would be fitting a oil temp gauge just under the dash by steering wheel. Sommerford do an oil sandwich filter plate for this, look at your oil temp before deciding if you need an oil cooler.
I have fitted a cooler but not plumbed it in, I have added two temp senders one as above and the other on the back of gearbox, with a single pole toggle to switch between them.
I really cant see a 1275 needing an oil cooler these days and you can do more harm than good if oil is to cold.
This thread gives a few opinions and refers to the CooperWorld article.
Both our current Minis run either 15/40 or 20/50 Mineral oil which we change about every 5,000 to 6000 miles, MPi does upto 10,000 miles a year and an 86 city that does 6,000 miles. Both have standard engine layout but are run all year round, the city is standard and the MPi has sump guard, front lamps and lap pod and gets pushed hard as well as run over 600 miles in a day for L2B and Beaulieu and neither have given problems. Neither have any of the other minis I have had over last 12 years well with regards to oil, gone through a few Water pumps and they have been driven many miles the same way but all have been A-plus. So my opinion would be if your going to fit an oil cooler fit a thermostat on it and change your oil to fit within your long hard trips, but run your oil in for about 100 miles before you push it hard.
