I got my new dial thermometer which is 12" long and factory calibrated to 212*F per my request. Tested it and boiling water is perfectly on!
Ran the 2 month old Briggs V-Twin for an hour (mowing lawn). Outdoor temp 74*F. Amsoil ASE 10W-30/SAE 30 wt. Stock "yellow" Briggs oil filter. Clean airfilter. Oil was at full mark on dipsticK. Sump holds 2 qts.
Right upon shutdown I removed the dipstick and inserted the probe so it would be right about the level as the "mid full mark" on the dipstick. Temperature read 178* F. Allowing the probe to go down the full 12" gave a reading of 205*F.
Called Briggs for the fun of it. They said that engine runs between 175*F-190*F. An oil cooler properly installed could knock off 40*. Tech said the heat in these engines is why they suggest going to synthetic oil; better heat transfer. Also, heavier oils retain more heat.
