What oil viscosity do i use in a 110cc jianshe motor

The description for Diagnostic Trouble Code (DTC) P1521 is "Incorrect Engine Oil Type." The Powertrain Control Module (PCM) is able to identify engine oil viscosity using oil pressure and oil temperature sensor inputs and will set this DTC if the viscosity is determined to be incorrect. Engine oil viscosity could be incorrect due to the wrong engine oil being added or oil contamination (with fuel or coolant). This code could also be set if there is a problem with the engine's internal oil pressure. Lastly, this condition could also be caused by a PCM software issue. There appear to be two software updates to address the false detection of the P1521 DTC; they are on Technical Service Bulletins (TSBs) 18-008-08 and 18-035-05. If the software is already up-to-date, I would recommend starting with an oil change using oil with the correct viscosity.

The "viscosity" of a lubricant refers to its ability to resist flow. There are two cases, either the viscosity is high or it is low: the lower the viscosity (0W/5W), the more friction is reduced, providing energy savings.

First 75w-140 is gear oil. Not intended for motors. First number is cold viscosity and second number is warm viscosity.

If oil is old it loses it"s viscosity or thickness when hot, maybe renew oil even put higher viscosity oil in motor.

5-20w is what the Manufacturer recommends and I would stick with that but go to synthetic as it is just better and really does not cost that much more as you can extend the service interval. This has the added benefit of less hassle in your life as well.

Hi,
Please check your oil type and oil level. You may use wrong oil ( viscosity need to cross check with car make). Usually you can avoid this problem by using a higher viscosity of oil).
Regards

Motor oil thickens when cold- on very cold days, some grades of motor oil can be nearly the consistency of honey. It takes time for the oil to make its way from the oil pan to the top of your engine.

The ticking you hear is usually caused by the valve lifters running nearly "dry" - meaning that they are getting very little oil. As your Cruiser warms up, the oil thins and makes it "up top" much easier, so the noise decreases.

Make sure that you are following your manufacturers recommendation for the grade and viscosity of oil (example: SG SAE 10W30) for the temperatures you are operating your car in. In extreme cold weather environments, such as Chicago or Milwaukee, you may want to use an even "lighter" oil (example: 10W20 instead of 10W30) - you just have to be certain that when spring arrives, you go with the higher viscosity oil- your manufacturer normally covers this info. The grade (example: SG) is very important because it refers to the detergent content of your oil.

No vehicle manufacturer that I am aware of recommends a "straight grade" viscosity oil (example: SAE 30) in cold weather. Multi-grades, which act "lighter" in cold weather are called for.

The "W" in the oil viscosity designation means "winter" - it is the viscosity of that particular oil at 0 degrees F..... For example, "10W30" oil is as thick as an oil with a viscosity of 10 at 0 degrees F, and is as thick as an oil with a viscosity of 30 at 70 degrees F.

Pretty Cool, Huh?

It is not a good idea to use any oil thickening additive (STP, motor honey, etc...) in cold weather because they tend to add even more viscosity.

"The Court is out" regarding teflon additives such as "Slick 50" to your oil- the principle sounds good to me, and I have used them myself. Personally, a similar product has seemed to help tone down the "startup ticking" I myself have experienced.

now ford has came out with a memo recommending 5w20. Ford Motor Company reports that the company's switch from recommending 5W-30 viscosity motor oil to 5W-20 viscosity motor oil has saved 700 million gallons of gasoline since 2000. By reducing load and internal friction, lighter viscosity 5W-20 motor oils reportedly increase fuel economy by a half mile per gallon. In addition, Ford reports its use of 5W-20 oils has reduced carbon dioxide emissions by about one million metric tons a year.
Note: Ford issued a TSB (technical service bulletin TSB 02-1-9) regarding the 5w20 superseding 5w30 Owners Manual specifications. Applies to the majority of the car products back to the early 1990's.
So in short in your manual it may say 5w30 but now they recommend using 5w20.
if you need further assistance please let me know, Thanks, MIDwest-TEK

Most any 5w-40 fully synthetic oil with be fine in your car.

Depends on the tempurate where you live,

MOTOR OIL VISCOSITY RATINGS

Viscosity ratings for commonly used motor oils typically range from 0 up to 50. A "W" after the number stands for "Winter" grade oil, and represents the oil's viscosity at zero degrees F.
Low viscosity motor oils that pour easily at low temperatures typically have a "5W" or "10W" rating. There are also 15W and 20W grade motor oils.
Higher viscosity motor oils that are thicker and better suited for high temperature operation typically have an SAE 30, 40 or even 50 grade rating.
These numbers, by the way, are for "single" or "straight" weight oils. Such oils are no longer used in late model automotive engines but may be required for use in some vintage and antique engines. Straight SAE 30 oil is often specified for small air-cooled engines in lawnmowers, garden tractors, portable generators and gas-powered chain saws.


Basically for your car I would run 5W-30, this keeps you covered in warm and cold climates, 10w-30 is the best choice if you live in a climate with temperatures that never go below 0degre''s Farenheight.


Hope this helps
