Question about Electrical Supplies

Frequent top up and low oil pressure guage.

I am a supplier of high quality lubricants which has meet various specifications like; the API, MB228.3, and NIS, with after sales services. I currently supply high quality lubricants to different generator suppliers all u Perkins power engines.

I currently have a problem for which I need your help. Two suppliers of the same type of Perkins power generator is buying the same brand of lubricant; API CH4/SJ, SAE 15W/40, KV@100C @ 15.80cst, TBN 10.8mgKOH/g. The first is enjoying the oil without any problem, while the second is having the problem stated below.

The frequency of top-up has increased and the oil pressure gauge after service drops from usual point 4 to point 2 equivalent to 50% drop after 3-4 days of service.

The question here is; what is going on, this is two same Perkins power generator with the same oil in use. While one has no problem, the other has drop in oil pressure and frequent top up. Like we do to all our customers, we offer free technical service which include testing of the oil at regular interval. While the oil in both cases show very good performance, the issue of low pressure gauge and frequent top up is what I find very difficult to understand.

Please, can you offer me any form of advice on this issue. I will be very great full if you do.

If it will be of importance. The power generator with the problem is operated in the northern part of my country where we are experiencing low rainfall and high temperature. Ambient temperature during the day is about 35 - 45C.

If the oil need frequent topping up it can only dissapear in 2 ways a leak or the engine is very worn and is burning it.
a worn engine is also a cause for oil presssure dropping once the engine has warmed up probably worn main and big end bearings on the crankshaft as you will know oil is thicker when cold so oil pressure is increased

INSUFFICIENT OIL OR POOR QUALITY OIL RESULTS IN PREMATURE WEAR OF THE ENGINE. Checking the engine oil level The engine oil level can be checked when the engine is cold or warm. To check, place the motorcycle in an upright position on a level surface (center stand). If the engine is cold, the oil level should be visible at the lower edge A of the inspection glass. If the engine is warm, the oil level should be visible at the upper edge B of the inspection glass. Add engine oil if necessary. !

Hello i have a 97 chevy with the vortec 5.7 when my truck sets overnight first start it knocks really bad and gets louder the faster i go until truck is warmed up then goes away i use a high quality oil...

Locate the sensor for the oil light. It should be on the back of the block roughly in the center, I believe. Either T into it or replace it with a mechanical oil pressure guage. This will likely tell you that your oil pressure is low, especially when cold.New pressure is 30-35 PSI. My suspicion is that you are below 20 PSI which would be normal for high mileage or abuse by a previous owner. If the pressure is down near this,20PSI, then it is time to start looking at either a rebuild or replace. You could prolong it by going to a heavier oil, either 15W40 or maybe even 20W50. They will provide extra lubrication and make the noise go away. If you live in a cold climate, I would suggest a block heater with these oils.

Oil pressure low stop engine and check guage

Fist check oil level, the sensor is a pressure switch worked by oil pressure, hopefully the sensor has gone faulty. The oil pressure needs checking, if the oil pump or relief valve has gone faulty, the engine is being starved of lubrication and is causing internal damage. It is advisable NOT to run the engine till the pressure has been checked. (hope it's the sensor)

What type of oil and how much do I use with the honeywell 1000w generator?

Engine Oil Recommendations

Use 4-stroke oil, or equivalent high detergent, premium

quality motor oil certified to meet or exceed U.S. automobile

manufacturer's requirements for API Performance

Class SF or better. SAE 15W-40 is recommended for general,
all-temperature use.


Engine oil is a major factor affecting engine performance

and service life. Non-detergent and 2-stroke engine oils will

damage engine and are not recommended.

• Be sure to use engine oils specified under "Engine Oil


It is very important to maintain proper level of engine oil to

keep engine in good running condition.

• Check engine oil level prior to each use. Refill engine

oil if oil level is low.

FIGURE 17: Recommended Oil Viscosity

Crankcase pressure can cause hot engine oil to

spray out of engine fill hole. Hot engine oil can

cause severe burns.

• ALWAYS stop engine before removing the oil fill cap.

I need an oil change and I cant find an oil that has SG in the label. What should I use?

You can use oil with an API rating of at least SG and therefore can use today's oils with an SN rating. The API service rating is basically a classification assigned to signify the oil's ability to reduce friction and oil consumption, improve emissions, and provide better lubrication. The API ratings are backwards compatible, but not vice versa, meaning SN will work for SG but SJ will not work for SM.

What is the most practical synthetic motor oil to use on a 2010 harley trike

You can use most any synthetic oil as long as it meets Harley's specs provided the bike is powered by a Harley engine. The fact that it's a trike has nothing to do with the engine lubrication requirements. Harley-Davidson's Syn3 synthetic oil is what H-D recommends. But, you can use any synthetic oil as long as it is 20W50 weight and meets API SG/CG4 or better ratings. The CG or better rating is what you are looking for. It is a rating for oil sufficient for use in a diesel engine. There are several manufacturers that make this type of oil. Mobil makes it's V-Twin Synthetic, Amsoil, Royal Purple, and many others. Just make sure it's rated for use in diesel engines. It has the "high pressure additives" necessary to meet Harley's specs. But, use of an unapproved oil may void the warranty on your 2010 engine. Good Luck!

Repsol MOTO Gasoline Motor OIl,4T,Sintetico synthetic blend 10W40

Repsol Moto 4T Sintetico Synthetic Oil - 10W40

Synthetic blend lubricant with high thermal stability, designed to meet the needs of the most technologically advanced 4-stroke motorcycle engines.
  • Excellent starting and lubrication in cold conditions due to its low viscosity.
  • Meets JASO MA API SJ requirements.
Its fine to change your oil with synthetic, Just be sure that you use synthetic from now on... I don't think its advisable to switch back to regular oil after using synthetic.

Low Oil Pressure on 1992 Chevy 1500 Pickup Truck

Hi! The problem you are outlining is very similar to the Rover V8 (Buick engine). We Brit's are used to the low oil pressure when warm. I presume a complete oil change engine flushed with new replacement filter has been carried out? Maybe a top quality synthetic oil with additive may help. You may take it a little further and replace the oil pump with an after market performance up rated one. If you really are worried about low oil pressure damage whilst in low rev's try Molybnenum Disulphide an oil additive which really reduces friction metal to metal wear particulary in the situation you are describing.
That's the best I can suggest at this moment.
Good Luck! and Happy New Year!
