Jan 6, 2017 路 So I have 2 Honda Civics, have always used conventional oils, sometimes blend of 5W20 with 5W30 or plain 5W20. Question is, does anyone has UOA or results showing that 5W30 or 10W30 or 0W30 or 0W20 can be used and are better? Honda suggests to use 5W20 both of them. Also, should I change the grade based on temperature and weather or stick to
Mar 20, 2021 路 This video is the sequel to a 100k engine failure (not my van, not my video), on some mechanic radio show the guy talks as if he has some experience and insists that the 3.6 pentastar engines in these vans will fail if you run the spec'd 0w20 oil. I presume suggesting that its too thin and over time leads to some sort of accelerated wear. Apr 5, 2020 路 The 0W20 has a viscosity rating of 20 at 100 degrees Celsius while the 0W30 has a rating of 30 at 100 degrees Celsius - meaning that once heated up to running temperature, the 0W30 will be thicker than its counterpart. This difference in viscosity will affect fuel economy as well as engine protection; generally speaking an oil that is too thinFeb 15, 2013 路 Based on what I learnt from here and elsewhere, I am going to use 0W-20 on my next oil change. The only reason that I can think of why people are using 5-20 or 5-30 instead is because the viscosity of the oil in connection with the outside temperature where it is much warmer/hotter. Engine parts don't always want thinner oil, espec
Mar 17, 2021 路 The heavier viscosity compensates for the previously mentioned fuel dilution at the end of the oil change interval, so it's still a 30 wt oil instead of dropping down to a 20wt Food for thought, a 0w20 at 20F is still heavier than a 5w30 at operating temp. If Dexos D flows when cold then a 5w30 will when hot. . 340 701 355 394 587 772 609 78
