Well i did some research on this topic mainly because i want to select the best value oil, From my understanding;I thought long and hard before starting another engine oil thread but I was wondering if anyone on here has used an ester based oil in their S10 - or any other bike for that matter?
As I understand it according to API, group 5 oils are ester based and engineered for high performance engines and therefore afford a greater level of "protection/performance" than group 4 oils which are fully synthetic.
Brands of oil don't really mean anything to me - names are unimportant, some people swear by Castrol/Mobil/Motul etc, that's their choice and I've no argument with that. I choose my oil by the specification but I've never heard anyone talk of ester tech in the same breath as engine oil, hence my question.
The stuff I've seen is API SL & JASO MA/MA2 spec. so it meets the needs and is £28.49 for 10 litres, my head says it's right but I would just like to hear if anyone has real world experience of using this type of oil.
Ester core oil group v is good because of its ability to remove all the stain in the engine better than other syn, bring out performance.
PAO is oil group v is good also similar function. Then Group 3 is synthetic base, and 2 1 is dinosaurs fossil mineral.
Assuming we talking about multi grade oil xxw x0, is like cocktail mixed which they don’t tell you the formula, what’s inside, knowing systhetic base is better, so look for 100% synthetic label, not full or semi synthetic, technosynthesis . The oil company mostly using group 3 oil (cheaper) as a base and add up PAO, and or Ester + addictive @ which a amount they don’t tell you, we pay the price for purely marketing brand. Motul 7100 is Group 3 +4 + ester a bit. 300v + more ester( what % don’t know) Better base oil will result in oil stability in various temperatures.
API,JASO,.. this one is the basic standard and envionramtal standard, phosphorus, zinc, reduction.. just follow the manual or goes higher.
When i purchase oil I look for its viscosity index (ASTM D2270)higher is better making its stabilize at wider temperature range, and Kenetic Viscotiy at 100C, lower is more HP, and Viscoity at 40C higher is better protection in cold start, and what brand what model depends on your location; price is vary.
I’ve been using Motul 300v Ester oil, yeah i love it smooth, engine run very quiet, really love it but very high price. VI is at 160, vi 40c is 82.3, Vi 100C 13.3 mm/s, compare this to the other well known brand that i use and its 1/3 of the 300v’s price. VI 161, Vi40c 82, Vi100c 13.1 mm/s.. So why pay more for almost same result. However, if my goal is for race I’d pay for 300v because ester syn will clean indside the engine for more smoothness better than PAO.
Hope this help, this is just a basic info, not oil expert but just looking for the good value best performance oil.
