Can i use 10w/40 4T fully synthetic in my 2009 TE250

Hello everyone first post on here, my names Gary , ive just bought a 2009 TE250 and am wanting to do an oil / filter change , the manual states 10w/60 , will using 10w/40 shell advance 4T fully synthetic cause any problems , I can get the 10w/40 for £25 for 4 litres, the 10w/60 is around £49

once again hello and thenk you in advance for your replies

I've run synthetic 20w50, 10w40, 0w40 and a mixture of 20w50 and 0w40 in my 450, I have almost 17,000 miles on it.

Yes you can run 0W40, 5W40 or 10W40 and your engine bearings will actually run a little cooler. Look around for Shell Helix if it is available, usually in 5W40. (0W40 is the preferred grade currently at our shop).

Go for it. A semi syn is also fine for trail riding

thank you lads

Been going to change from Motul to Castrol engine oil as Motul is a bit hard to get in the town were I live. Know that in the manual for te250 2011 they recommend 10w50 Castrol but can not buy in Australia so told not imported for some reason unknown. So does anyone use a Castrol that they recommend.

Use 0W40.

I use Rotella T6 Full Synthetic 5W40 in my KLR. Shifting is butter smooth. Better than the Mobile 1 Synthetic Motorcycle Specific Oil. A lot of KLR guys swear by it. And it's cheap. In my TE511 I'm using the Mobile 1 European Car Formula 0W40 mentioned above. Seems pretty good.

I have used Motul Full Synth 10w40 on my 310, our motors are identical apart from ~50mm bore. I have foud the oil to be excellent.

Got Penrite 5w-40 full synthetic in shed been using it in the young sons quad don't know weather to give it a go or not. Does anyone use Penrite oils in there bikes.

Changed to Penrite 5w-40 hope will be ok. Thanks Tinken for the confidence to try it mate, still a bit concerned about the change?

I like Penrite 5W40, they have some new versions out too like enviro and everyday plus. The enviro is very similar to M1.
