Redline Synthetic Motor Oil 10W30
|Best all-weather viscosity grade for gasoline engines in cars and light trucks that are driven on the street on a daily basis. Reduces turbo lag and provides more power and economy while providing thicker bearing oil films at operating temperature than a petroleum 10W-40. Best all-round, synthetic oil for stock or slightly modified engines in high- performance cars that are street-driven. Best choice to replace a 5W-30 or 10W-30, petroleum-based or other-brand synthetic oil if maximum durability is preferred. Acceptable for engines that are occasionally operated in extreme cold weather.|
Best general purpose oil!

Been using Redline lubricants since the mid-90s, and they've been great. I used to use 10W40, but in recent years I've moved to 10W30.
In terms of engine protection, the Redline 10W30 has the shear strength greater than almost any synthetic xxW40 synthetic apart from Shell Helix Extra that's not available locally. I don't drive hard, so I'm comfortable using 10W30 instead of 10W40.
Choosing 5W40 does not make sense here where the coldest morning is not going to be lower than 20C. Wider viscosity oils need more thickeners and thicken at higher temp, which is not ideal.
