Low oil pressure makes me nervous

Just for info, there is a reason for this.... full synthetics have a much more stable viscosity over a wide temp range. The lower weight viscosity number is tested at 100F, so down at room temp, the standard oil has thickened up while the full synthetic has not and so that is why it seems thin and runny when you pour it. That seemingly 'runny' synthetic will actually be MORE viscous at 200F than a 50W standard oil will be at that high temp.

The styrene molecules are formulated to never thin more than the lower grade number and never thicken more than the higher grade number. Synthetics are a more uniform molecule than conventional oil, more stable under extreme load and pass through filter media better.
All my years in parts gave me oppurtunity to speak to many company reps. Learned a lot.
Couple things to pay attention to, semi synthetic/synthetic blend is about 5% synthetic

Cheap oil is exactly that. You get what you pay for.

Pick any forum,any make and you will find almost the exact same discussion. End result is always the same. Car guys are crazy. Just not as crazy as horse people....
