My fg6000mk is 5years old and has been ran about ten minutes should i change the oil and what weight for winter use

These engines are known for their problems with the variable valve timing mechanisms. First thing is to make sure you're using the right weight oil because the mechanism depends on oil pressure to change valve timing. If using the wrong viscosity, you screw up the valve timing. Also, neglecting oil changes can do the same thing. So can sludge buildup. Remove the VVT solenoids and check for clogged solenoid screens. None of the symptoms or codes you listed point to a bad computer. They all point to a problem with variable valve timing.

heavier oils are fine in warm summer months, 10W30 or 10W40-
all cars ran on these oils summer or winter for years. Newer vehicles are designed for 5W oils and you should use a 5W oil for them in the winter months

Looking at the size of them I would say between 250-300 no per leg of ten weight fork oil.

Changing the weight of oil or going synthetic

the clattering is most likely valves rattling until the oil gets up to top of engine,recommend change the oil and filter,use a good filter like fram oil filter,i've always used castrol 30 weight oil in winter,then summer 40 weight, also recommend you add lucas oil treatment,1 bottle,add with your oil change for top end lubrication,the oil stays and clings onto valves and adds a whole lot more of top end lubrication to your engine than just regular oil.it's just a treatment,i have a 1994 ford explorer with 450.000 miles on it.just trying to see how far i can go with original motor.but i always use castrol oil,fram oil filter and always add lucas oil treatment every time i change my oil.thank you for choosing fixya.com good luck!

5w 30 or 10w 30 during the winter. After an oil change... check your oil after 200-300 miles of use. Is the level the same? If so your weight is fine. If it drops, it's to light of an oil and your engine is now "drinking it" like fuel, move to a heavier weight. As far as Changing between winter and summer. Changing Oil weights is not bad for your motor so if the winter you go with 5w 30 and it works, great, shoot for the same during the summer. If it seems to "drink it" during the summer using this weight, go up to the next (10w 30)

That being said. Changing from natural oil, to synthetic, back to naturual , or vice versa... swapping back and forth between these KINDS of oil has been known to cause damage. so whatever weight you decide on, stick with one "type", natural or synthetic.

Use a pressure gauge and make sure you have at least 10 psi, if you do then replace the oil pressure cutoff switch if this switch is bad no oil you put in it will fix the problem. If you don't then you have internal engines problems.

A lighter weight oil will only make the matter worse because its thinner and could actually cause the pressure to drop even further. If you have a low pressure problem you could try a heavier weight oil but its only going to increase it a little bit.

It is not the oil switch you need to adjust the heads open the side and check on the settings for both in and out and adjust them according to the manual...in the winter sometimes they do not like heavy oil so check the oil weight and try lighter one

allot the generators take 30 weight but thats a guss in the winter i had go with light weight.
i am on my second colman i lived woods for years with no electrci other generator 30 weight is heavy stops less wear tear on the insides. But winter time comes i had go lighter becuse oil was like malassas. And then i could not pull it to start it was so thick and heavy the oil in winter
go there web site look up ore try 1800 number for them to get

O.K. Let's use 20 weight for example. A straight weight oil is just that, a straight 20 weight in viscosity, it doesn't change when it gets hot or is cold, so it won't thin when heated. It will read
sea 20 on the container. A 20/50 has a viscosity that changes when heated. When cold it is a 50 weight, then as it heats up it thins to a 20 weight. A 20/50 might not be too bad to run in this situation, but the viscosity breakdown is quicker with the mixed viscosity oils, so I generally recommend running a straight weight, such as 15 or 20 in the winter, and a 30 or 40 in the summer. Keep in mind that the oil does not thin, so if you have extreme cold in the winter, the car may not start very easy. If it doesn't, then you can go to a thinner oil. In the summer, if you have extreme heat, you can go with a thicker oil if the engine has a little noise, or running hotter than usual. Just remember, the lower the number, the thinner the oil. Running a thicker oil in yours, should cut down on the oil consumption.
