I'm just wondering about this...
when i got my first engine oil changed at the mazda original dealer, the technician changed my oil to 5w-20 engine oil grade. i know it won't harm my engine, but is 5w-20 a good engine oil? it is because my oem mazda miata owners manual says it recommends 5w-30 grade engine oil. is that ok?? once again im just wondering and curious
any good feedbacks are welcome
thanks in advanced
