Oil Change question

[BananaDan]

So I changed the oil today for the first time since she's been back on the road (third oil change actually but I didn't do the other two myself).  When I had the engine rebuilt I went with the MP extra capacity oil pan, which I'm told is 6 quarts including the filter?  It seems to jive because the oil I took out just about filled up the 6 empty quart bottles when I was done.  The interesting thing is the dipstick reads add 1 quart, I have a standard repro dipstick.  I'm thinking that the standard repro dipsticks don't read accurately for the extra capacity oil pan?  I wanted to check because I am pretty sure I don't need to put another quart in her, but maybe I do?.  If my suspicion is right, do they make a dipstick for the extra capacity oil pan?

I put in Valvoline VR1 Racing Oil, 20W-50 with a bottle of ZDDPlus additive.  The oil pressure gauge seems about the same as it was before the oil change.  It reads about 40 idling and 50-60 while driving, accounting for the crappy accuracy of the stock gauge of course.

I just did some reading on this site and it seems that the pan is a 6qt. pan and the filter is on top of that so it should take 7 qts. and I guess the dipstick is accurate.  I guess it is 6qts. plus the filter, not 6 qts. with the filter.

6qt pan, plus one for filter

yes as we discussed

[BananaDan]

Yep, thanks for sorting me out.  I'm good.  I guess it was too good to be true that a case of VR1 would provide me a nice even 2 oil changes.

Dan,

FYI - I use the VR1 race oil also that has the added zinc.  I was told not to use any zinc additives if I used an oil with the high zinc content in it as it could be more harmful than good.  Too much zinc could cause problems my engine friend said.  He said that the VR1 has enough of the additive zinc so you wouldnt need any extra.

Brad Penn  SAE grade 20W-50 is another good oil with plenty of zinc in it. It's what I use.

I've always had good luck with Royal Purple although some don't like it for whatever reason.

[Fred]

I've tried to find out the zinc content in Royal Purple with no success. They don't seem to want to divulge this info so I'm a bit skeptical.

Maybe because its double the price of the VR1

[BananaDan]

Hmmm.  Has anyone else heard that adding a zinc additive to a high-zinc oil like VR1 could be a problem?  I told Mike Bonsanti (my speed shop) that and while he did say it wasn't needed, he didn't say it would cause problems.

I remember reading it somewhere through one of our members in the NJ Region AACA who brought a published article to a meeting with the need for the zddp additive and in the write up it said that while not enough is a problem, too much can add up to problems too.

[Just 6T9 CHGR]

Dan, you'll be fine....I'd be more concerned with the fact that you were a qt low

Just don't use the zddp next oil change if you don't have to, or if there is sufficient zinc in the VR1 oil already.

You a right.

[firefighter3931]

Dan, you won't hurt anything by adding a bottle zzdp additive to 6qts of VR1 oil.  The Hemi repro pan holds 6 qts plus whatever the filter holds. I allways used 7 qts and called it good

OK, thanks all.  I'm leaving her as-is and will add the extra quart this weekend.  I guess I have two bottles of ZDDPlus left that I won't need...   

[Paul G]

I add one bottle of ZDDP with 8 quarts of VR1. I have read that even VR1 does not have the same amount of zinc that regular oil used to have back in the day.  The more you research ZDDP, the more confused you will get. I did.

[Fred]

It's mind boggling alright.

Which is why I use Brad Penn 10/40 and call it a day.  Formulated with the right amount.

Psst...
I'll take 'em back off your hands, Dan.

I run bradpenn 10w40, but every person posts a different oil analysis that says the other guy's oil doesn't have enough additive. So I run a bottle of zddp in my car as well. No wiped cam and I put a lot of miles on the car. With the 10w40 I sit at 85lbs oil pressure cold, at temp I sit at 40 idling(1300), 60 cruise(2800), 80ish at (7000)

[Fred]

Does anybody use Brad Penn 15w-40?. I'm very curious. It's never mentioned.

[Chryco Psycho]

I have used Brad Penn oils , seems like a good product 

[Fred]

Yes it is a good oil, I use it myself but I use 20w-50 and was just curious as to whether anybody acually used the 15w-40.
