On a short commute, there's not much you can do to get the engine oil up to temperature .
In the cold (to us!!!) weather here (all 6-8 weeks of it), even with the oil cooler blocked off, the oil temp rarely gets to 200 F. on my commute to work with the '81 R65 .
I'll have to swap the oil indicating dipstick over to the '82 LS without a cooler and see what temps I get .
