I noticed on one of the old Valvoline logos it said Pennsylvania Crude... So why hasn't Valvoline ever gotten the sludge rumor if they used to get their oil from Pennsylvania?

On the flip side of all the discussion on M1 and every other synthetic brad out there, lets talk about Valvoline conventional. Hate it? like it? good uas? clean engines? dirty engines?

I purchased a 5qt jug of MC5000 at Walmart a few weeks back..then I went to Advance Auto today to get my filter and they had the 15.99 deal on Valvoline Premium with a filter, so I got that too..LOL I prefer to stay consistant even though many of you have proven that switching brands does no...

..is their add pack top notch compared to the other brands?

Been a long time PYB user, but ocassionaly run other things..and actually runnng Castrol GTX 5w30 for the next 4 months.. I know its too hard anymore to comare one SM rated conventional to another since the lines are blurred and they all are great..But is there any reason to assume GTX could be...

Is Pennzoil and QS conventional add pack better than Castrol GTX?

My car runs smoother on PYB than any othe oil. Is this also just in my mind? Or, does the Grp II+ base stock of an oil make a diff?

I've always noticed in my Chev Lumin when running Maxlife synblend that the engine will ever so slightly shudder at idle, and I was due for my next OCI, giving PYB a try and the engine runs smoother than I've ever experienced. Is this placebo?

Here's another piece of info Johnny provided me in regard to HM oil when have a discussion with him... *************************************************************** When HM oils first came out, most conventional oils were made from Group I base stocks. The sulphur content in Group I would over...

A long time ago, Johnny told me the following: ************************************************************** When a seal goes bad nothing is going to stop it from leaking, except replacing it. HM oil originally came out because of the valve stem seals on V-8 GM motors. They use to get hard and...

I found this old thread I created a long time ago...not sure why I state "first post" when I had 616 of them to begin with, but.... PYB still a Grp II+?

I've seen several people recently disucss how they notice reduction in MPG when using Maxlife synblend. I havn't noticed anything in regard to this. My vehicles seem to get exactly the same fuel economny as when using a straight non-HM conventional. Anyone else in my boat? those of you who have...

Isn't Pennzoils guarantee more attractive given the fact the warrenty applies to their conventional? With Valvoline the 300k warrenty only applies to their syn. no?

Originally Posted By: mechtech2 Seems like a good upgrade. But it makes me wonder how in the world they designed and OK'd the extant oils knowing there were problems. Can you or someone else clarify what you mean by that. Interested to know. The new gf-5 has problems?

I read the following on their web site and want to know if this means that with regard to HM oil (only in regard to seal issues), will HM oil not be as neccessary to use anymore with this new spec??? ***********************************************************' Seal Compatibility Seal...

Anyone using this stuff? Like it? I'm due for an oil change. Went to Walmart for Maxlife and just didn't want to spend 16 bucks for a blend when I know as a member that conventionals are a blend as it is now. They were out of Pennzoil 5w30 so I grabbed the Quaker State for 10.50 for the jug...
