Using 20/50 oil will not hurt anything unless it’s used in very cold weather with short trips involved, etc. But and it is a big but! My feet are only good to about 20f or so, and with a 30 mile commute, and speeds around 70 as common for much of it, i rarely push even to that 20 deg mark.
Valvoline 20W50 Motorcycle Engine Oil 1 Quart
It really comes down to personal preference.
I do have a question or two though.
Summer its nothing but spectro 20/50 It stands for “winter” and that is the key to understanding viscosity grades. The 50 describes what the oil will behave like at operating temperature. I'm happy with a 10 psi per 1000 rpm rule.
Been formulated to help extend the life of your engine.
Each of these numbers are essential to understanding how that particular oil weight will perform in winter and summer driving conditions. The 20w indicates how quickly the engine will start when cold or in cold weather. Really, the w should remind you that in winter, in a cold place, you may have to consider it. The first number is the winter viscosity rating, or the viscosity when your oil is at zero degrees fahrenheit.
The number before w stands for the viscosity ( thickness ) of the oil during winter when it’s very cold the number after w shows the oil viscosity when the engine is in operating temperature or during hot.
20w50 motor oil is relatively viscous and thick. Finally, for pilots in colder climates, it is more important to use a multigrade oil especially in the winter because of oil cooler congealing. If you want thicker oil and the temperature only dips below 30 degrees f for a few hours a night in the winter, you should consider thicker oil. This is the value you should be most concerned with.
For the sake of understanding let us take this colder temperature as 0 degrees celcius;
The third letter ‘y’ stands for the viscosity number of oil at engine operating temperature. The w stands for winter and is a measure of the coldest temperature at which you can safely start your car. With this setup i use 20w50 oil, the same as most use in evo's and twin cams. A 20w/50 oil is much thinner at high temperature than a 5w/30 at a low temperature, so the viscosity will not hurt your engine.
The comment about covering up engine problems with 20/50 is correct but should have nothing to do with how the engine actually performs.
This also eliminates the outside oil lines. Like negative 20 degrees instead of negative 5, or something like that. Today’s motor oil is formulated to be 80% base oil and 20% additives. This refers to its fluidity or thickness.
Most 20w/50 oils do not meet the anti wear requirements of modern engines!
This way, they are able to pass tests that meet the 0w rating. The 50 refers to the thickness of the oil when the motor has been running for a while. I run 20w50 all year round. The letter in between ie ‘w’, stands for winter;
(for lhr in winter both ok,, as it nevers snows here,, but 20 /50 for rest of the year except winter.
With this innovation in oil. If the car ran great then why did you have the engine changed? I have difficulty getting hold of this engine oil in malaysia. The borderline pumping temp (true limit) is significantly lower.
A typical winter grade was 10w.
Typically, a 5w oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold. They are 20w/50 and 5w/30. I use an evo cam and lifters with rocker arms that allow push rod top end oiling. The base oil can either be conventional, synthetic, or a blend of both.
10w stays fluid at colder temps than 20w.
The first letter ‘x’ stands for the viscosity number of oil when the engine is cold. Forty years ago, there were winter grades for cold weather and summer grades for warmer weather. 10/40 for cold,, which is better depends where you live. For the sake of understanding take this operating temperature as 100.
Any one who has experience of using the two.
Oil weight is expressed with two numbers (i.e. Can i use engine oil with other specification for the supercharger? Using chevron delo 400 15/40 here in ri for winter use. Derek, your mom will tell you that the range for 20w50 is about 15f to 105f.
