Engine Oil changing questions

[rudra2k14]

My Rc390's
1st oil change -1000kms
2nd oil change - 3.5k kms
3rd oil change - 4.5k kms

now i am running 5.3k kms.

Should i do 4th oil change.?

Note : Fast oil changing is bit costlier for me.

HELP!!

You don't need to change that often bro, change every 5-8k kms. Do your next change at 10k and then every 5k kms.

 

[rudra2k14]

Are you sure? that won't affect the engine?

1000 km is 620 miles, I would change the oil every 2000 to 2500 km or 1200 to 1500 miles if it were me. The bike only holds 2 quarts so I would change it sooner than I would on a bike that holds almost twice as much. Just my opinion

If I'm not mistaken the official time given by KTM is 5,000 miles or 8,000 kms, why don't you check in the service manual?

Right! I'd suggest simply following the manufacturer's recommended service intervals.

Factory scheduled oil change intervals are;
620mi
4650mi
9300mi
Every year

Agreed that at your stage, less frequent (absent race or track use) should be fine, so long as you're using the spec oil or equivalent.

 

[Bagwell]

Wow, 4000 to 5000 miles sure seems like a lot for 1.8 Liters of oil.

can someone verify this please

"Factory scheduled oil change intervals are;

seems to good to be true.

YEP.. Page 79 of the owners manual
every 7500Km/4650miles or every year

I would change mine every 5000 Km's if i was riding more than that in a year.. and every year if i wasn't.

Yeah and way more than I will subject my 390 to... 1.8 liters of oil just isn't that expensive...

^^^^^
This. I'm not likely to change every thousand (barring track use), but every couple-three thou would be my ballpark interval.

(And no, I'm neither a petroleum nor mechanical engineer, and I didn't stay in a Holiday Inn Express)

I've seen the 'oil change' thread on every forum for every vehicle I've ever had and it's usually all over the place with false claims and opinions. The answer is always the same regarding what is 'required'...look in the vehicle manufacturers manual which will provide the MAX recommended interval. This is what the guys who DESIGNED the engine recommend and I'm am going with them. There is ALWAYS lots of variation on what folks are comfortable with...there are many who feel better about changing it more often which is fine. I have always had good luck using a top quality synthetic and a good quality filter which makes me feel better about going to the max for my intervals on all vehicles. With this engine design, KTM has 'recommended' their max interval....changing more often is a personal choice but not 'required'.

 

[CAZHEREDIA]

Are you certain that these intervals are correct?

Yes!

See post 11 above...if you don't have a manual here is a link (google is your friend):

Not sure why you would question this. I copied it directly from the manual. And others have repeated it as well.
In my manual it is pg 73. I would suggest following the link provided.

Before I replaced the cooling fan on my RC it overheated and shut off three times. After that I noticed oil consumption had increased to about 200mL per 200-300 miles. The heat, I feel damaged the oil in some way to cause it to slip past the rings so I changed it right away.

After fixing the overheating problem, consumption stays steady at about 100mL per 1000 miles or so. Oil is so good these days that if it doesn't overheat, you use the correct oil, and stick to the plan in the manual, you won't have any oil related problems.

Are you using the recommended motorex oil? It kinda is and I get it 35% off.
