I finally decided to poured in my FREE CASE of PU 5w40 into my 96 BWW ( not the whole case of course )
(Thanks Debbie!!)
Oil pours heavy, just as heavy as say Delo 15w40
Needless to say runs very smooth. Less noise than GC, M1 HM and Valvoline 5w40 and Rotella 10w30
( we'll see if it gets noisy towards the end like the Rotella 10w30 did )
No real news, just really a plug for Shell and Debbie!
