In short, it's up to you how far you wanna stretch your engine oil. My advice is no more than 7.5k KMs, Semi or not.

For semi, try no to stretch it at all. If possible 5-6K at most. The base stock of semi is almost the same as mineral with added "synthetic" components. Probably a bit cleaner than mineral but it IS NOT the high grade refined based stock that FS uses. So treat your semi as mineral when it comes to service interval if you want to keep your engine clean maintain long term performance.

Of course go ppl can go semi or mineral for 15K, no problem.....your luck and risk tho...

You can eat your fruit fresh and ensure vitamins are there or you can wait till it dried up outside.....eat no problem but the risk is very much higher that its contaminated and might have bacteria that can cause havoc within your body. Same with engine oil on cars. Change it out before performance start to degrade if you can afford it, if not change it after performance degraded but risk of negative after-effect  is always higher on the latter case.
