Yes, I give it 5 stars because it works as advertised but YOU DON'T NEED IT. I have a 1965 pontiac GTO 389 4 spd. and a 1977 Ford F-250 2wd with a modified 460 auto. After hearing all of the hype about flat tappet cam failure with SM grade oil I thought I would give zzdp a try. Then I got curious and called a petroleum engineer at Shell. I was informed Rroltella-T has all the ZZDP any car engine needs, that is to say the level is equal to SJ grade oil. It is a diesel oil and the viscosity is 15w-40 yet that's OK for an older vehicle with a high performance flat tappet cam. Quaker State defy has 75% of the ZZDP of Shell's and is a 10w-30 synthetic blend its fine for any engine built after 1995. I also checked with a fleet technician at my employer (Century Link) and was told Motorcraft diesel oil has a disclaimer on the label not to use on vehicles with catalytic converters due to its high ZZDP content. The fleet runs all the diesel engines with that oil and Cummins diesels still use flat tappet cams. The company maintains the fleet meticulously so much so we had Pinto's and Cavaliers go for 20 years and up to 225,000 miles. I am very particular of my 2 classics often getting complemented on their appearance and performance so I would never jeopardize their maintenance. As we have heard so many times before skip the additives and do it right.
