10w40 oil !!! Food for thought!

Guys you may have read some of my posts on here about the engine change I done. I genuinely think my problems started when I changed the oil to 10w40!! I had bottom end failure resulting in a very expensive new engine fix. I have spoken to a few mechanics about it and they agree. I ride bikes hard as I'm sure many of you do.
I looked on here and seen lots of people were using 10w40 so I thought that will do me as 15w50 is expensive, £50. How wrong was I!! I was ****** mad with myself for scrimping on something like this but what's done is done.

Take what you want from this but if it says 15w50 in the book it's probably for a reason. People say that it's for hotter climates and stuff but I say bollox. Use 15w50 lads

Same here. But I agree with Blade, 10W40 wouldn't cause that to happen, which normally suits the UK temps v-well. The oil quality API rating is a different matter though.
 
Just wanted to let others know of my problem. Wouldn't want it to happen to anybody else

Rendo,

Appreciated. What bike do you have, and what mileage did the dud engine have on it?

How long did you have it before it failed, and many owners in total?

Just wondering if it had been used and abused before you got it, hence it may have failed anyway.

The only real way of telling cause is to have engine analysed by a metallurgist, to define what broke and why
