“Curious as to what your thoughts are for the best protecting synthetic motor oil "off the shelf" selections”
“Curious as to what your thoughts are for the best protecting synthetic motor oil “off the shelf” selections. Got a 2000 GMC Sierra w/5.3L. Has 262,xxx miles on original motor,transmission,ect. Everything is stock and just want to keep it running great as long as possible. Also I don’t mind paying the premium price for synthetic motor oil as long as I know I’m getting a product with a quality BASESTOCK. Definitely do NOT want a high percentage group III hydrocracked basestock. Thank You.
“I was curious if the ester base would damage/deteriorate any of the seals,gaskets or plastics in the engine or associated parts?”
“I just bought a 2017 WRX and I’m looking to change the oil for the first time. A friend recommended Motul group v oil. I was curious if the ester base would damage/deteriorate any of the seals,gaskets or plastics in the engine or associated parts? The reason I ask is I’m an aircraft mechanic by trade and a lot of airplanes use a phosphate ester base hydraulic fluid (skydrol). I’ve seen that stuff chew up paint, plastic, composite, etc. So, when I saw ester and motor oil in the same sentence I became a little wary. Any assistance/knowledge you could share would be greatly appreciated.”
