5W-40 vs 5W-30 Empowering Your Engine's Efficiency – A Comprehensive Oil Viscosity Guide

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): I (A) = P (W) V (V) ซึ่งประสิทธิภาพการทำงานที่ดีระหว่าง 2 ตัวเลขนี้ หากค่าตัวเลขแรกที่อยู่หน้า W มีระดับต่ำมากเท่าไหร่ การทำงานในช่วงอุณหภูมิเย็นตัวก็ดียิ่งขึ้น (อัตราการการไหลดีกว่า) เช่น น้ำมันเครื่อง 5W-30 เบนซิน จะไหลง่าย ... 5W30 and 5W40 motor oils share the same viscosity at cold temperatures (5W), but their viscosity diverges at higher temperatures, influencing their suitability ... Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don't even need that if you are running shorter change ... Direct injection/turbo w gas dilution is the reason to change every 6 months especially running 0-20. Makes it even thinner. The most common engine oils used in cars are 5 and 0, also known as seasonal engine oil, which can be used in both winter and summer. 0W means the oil flows like a zero weight when cold ( W is for winter), 5W like a 5 weight when cold, the 40 is flow when warm. Not much of a difference. This video offers an in-depth comparison between 10W-30 and 5W-40 engine oils, analyzing their viscosity ratings, characteristics, ... 15W - 75W, 15W - 40W, 10W - 15W - 25W - 40W, 10W - 15W - 25W - 40W, 7W - 15W - 25W, 7W - 10W - 25W, 20W - 40W, 10W - 30W, 10W - 20W, 10W - 20W, 7.5W - 15W, 5W - ... I've done some reaserch and know that my Audi TT should be using 5-30W oil. ... and another. http://www.ebay.co.uk/itm/MANNOL-Audi-V ...
