if you’re using the correct viscosity oil, warmup is not necessary! And I’m just a girl!
All oil drains down to the oil pan when it sits in your drive way overnight....in cold weather it thickens along with EVERY other fluid minus your alcohol laced antifreeze. All of your moving metal parts within your drive train will be unduly stressed until the engine burning all of the extra fuel introduced into the cylinder by the computerized injector generates enough heat that in turn gets your oil and other fluids to near operating temperatures. depending on how cold your area is 2-5 minutes is fine...a good example is if you ever drove a stick shift and you try hoping in and just going in the cold...it is hard to shift because the fluid is thickened by the cold...once warmed up it shifts smoothly...if you plan on keeping your vehicle as opposed to just leasing (rid of in 24 to 36 months) let it warm up while you scrape your windows or get back inside to get a coffee to go...believe me you and your car will be much happier. No unneeded wear and tear and your car’s engine will last longer.
Not true, correct viscosity oil just makes the starter's job easier, and causes the oil to flow and pump better (maybe shortening required warmup) but does not replace warmup. You want to wait until wear parts are fully coated with oil. Additionally, expansion/contraction issues in the newer engines are not as acute as previously but still exist.
