Hi.My diesel electric generator has a sticker that says Change oil every 100hrs. Use 10w-30 grade CC. But I can't find this oil anywhere. The closest I have found are 10w-30 Mobil1 synthetic oil (API SM/CF) and 15w-40 Pennzoil gold (with diesel protection, API CJ, CI, CF etc. /SM). Which one should I use?Thanks!
You are not looking very hard,. Shell Rotella and Chevron Delo are all over the place
I beleive that CC is obsolete. Search diesel engine oil and find the one that matches your engine type.
