Need to change my '01 E430 oil so phoned local dealer looking for Mobil 1 0w40 which is the only oil the engine has ever seen. Parts guy told me MB switched to 5w40 (for any '98 or newer Benz) about 7 months ago and that's what they sell for $7.95/qt.
The only 5w40 oil I saw on Mobil 1's site is Delvac, which the guy assured me is not what they're selling.
I know the last thing this board needs is an oil thread so I'll delete it when someone with knowledge chimes in, but is this Mobil 1 5w40 exclusive to MB? (thus why it's nowhere to be found on Mobil 1's site?)
I appreciate any response.
