May be of interest to Mobil 1 users.
 

I just saw a flyer from "Auto Zone" parts store.
They have Mobil 1 on sale thru 12/25/17. Looks like you get 5 quarts and a filter for just shy of $30.00.
Ad says it is good for any of the synthetics including high mileage and does not specify a limit.
Might not be able to use the filter, but 5 Qts for 30 bucks sounds pretty good to me.
I am not associated with Auto Zone, in fact rarely go in the store.
Y'all have a great one !! :cheers:

Re: May be of interest to Mobil 1 users.
 

That’s a good deal if you include the filter. I just picked two 5qt jugs of Mobile One 10w-40 High Milage for $25 a piece at Walmart. That after I missed the sale at $19. :censored: Got the filter from NAPA a Wix 1324 for $7.

I just switched to Mobil 1 Extended and got it from WalMart at $25/5 quarts.

Re: May be of interest to Mobil 1 users.
 

Amsoil 10w-30 blended with Walmart Mobil High-mileage, Napa Gold, ...sometimes Amazon Wix 2-pack.

24 hr oil change method, hot, neodymium magnet on filter, drain catch can, lube door hinges.

It was posted recently Mobil reformulated and lowered the additives, so I'm going full AMSOIL 10w-40 from now on.
High Mileage was the recommendation, the Extended Performance did not meet spec ...but it has the "gold" cap. I wrote Marc about this to get clarification.

Re: May be of interest to Mobil 1 users.
 

3 items that may be of some interest ...

• Mobil 1 10W40 High Mileage - zinc levels are close to the recommendations for the LT5 (Amsoil 10W40 AMO is closer but not always readily as available)
• Once a year (maybe more often) Mobil 1 has a rebate promotion - $12 back for 5-qt jug as well as other rebate combinations. The last promo offer ended 10/31. If you caught the sale price of $20.00 and used the rebate you could have bought 2 5-qt jugs for $16.00 (max 2 rebates per household). Sometimes WallyWorld posts the rebate forms near the oil; otherwise, you can Google Mobil 1 rebates, find the current promo, download the pdf, copy your receipt, mail it in, and wait for the mailman to deliver your rebate.
• AC Delco filters prices dip close to $5.00 each (sometimes lower) at Amazon a couple times a year.

Re: May be of interest to Mobil 1 users.
 

I stocked up on the AC Delco filters from Amazon. Great price for a good filter. Thanks for the heads up on the rest!!

Re: May be of interest to Mobil 1 users.
 

Hadn't heard that about Mobil 1 cheaping out on the ZDDP.:mad: Well, no harm here; never put their stuff in my Z anyway. (I buy my Amsoil 10-40 from Marc Haibeck...because I CAN and we gots ta support the local sheriff, doanchaknow...:p )

Been having my oil changed (DD F150, etc.) for 18 years at a oil change joint. I change my own on the Vettes, and the oil joint used to drain my 5 gal Gerry can for free.

NOW they want $1/gal to accept used oil.:mad::mad: Anyone else have this problem??

Sorry....don't mean to hijack the thread.

Re: May be of interest to Mobil 1 users.
 

My town will take the oil at their recycling center. I brought in a 5 gallon jug full of used oil paid nothing.

Re: May be of interest to Mobil 1 users.
 

I gotta ask...
How come so many use 10W-40?
The oil cap on the engine and the owners manual say 10W-30?
Would like to think the GM engineers knew what they were talking about...
(but, sometimes I wonder?)

Re: May be of interest to Mobil 1 users.
 

Marc's recommendation 10w-40 for increased film strength.

Paul, if I lived anywhere near Haibeck Automotive I'd probably hang around the shop all day long, just to gain ZR-1 knowledge.

Re: May be of interest to Mobil 1 users.
 

Yeah, one always learns new stuff with a visit to "The Specialist". Just a few minutes more to the east, and Pete's shop is there. Or a few minutes west, and Dominic can be found fussing with his dataloggin, and Bob Gillig just a few minutes away....

Yep! This is ZR-1 country. We're not called the "FBI" for nothing! Some of the very best meet here for pizza several times a year! It's an honor to live here in such a concentration of talent!:thumbsup:

Re: May be of interest to Mobil 1 users.
 

Jealous lol!!! But that is one of the reasons I bought my Z, was the incredible community of people.....I'm going to have to drive up for a pizza night this summer.

Yup, that’s the one (and only) thing about Chicago I miss. Great bunch of people and great pizza! Ok, two things...

Re: May be of interest to Mobil 1 users.
 

I was trying to do a lot of research myself being a "new" Z guy... I read the discussions and articles on the "Mobil 1 High Mileage" having higher ZDDP, however when I went to the Mobil data site, it's showing the same as the other regular 10w30... I'm wondering if they've pulled the higher ZDDP out of the "High Mileage" as well.

The date on this document is March 2017.

Re: May be of interest to Mobil 1 users.
 

Interesting... looks like they changed it yet again.

Re: May be of interest to Mobil 1 users.
 

I use Amsoil AMO 10w40 in my Z.. I use Amsoil OE oil in our regular cars

Re: May be of interest to Mobil 1 users.
 

Oh great! I just switched to it.:neutral:
However, I am noticing an appreciable reduction in oil consumption.

Re: May be of interest to Mobil 1 users.
 

Just buy Amsoil and be done with it ;)

Re: May be of interest to Mobil 1 users.
 

I also run Amsoil 10w40, which I'm in need of changing btw....but I'll order it online, and it's here in a day or two. Good stuff.

Re: May be of interest to Mobil 1 users.
 

Yep, I order online and then go and pick it up at lunch usually (I am close enough to the Chicago location)

Re: May be of interest to Mobil 1 users.
 

I guess the question is how many of us have unknowingly continued to use Mobil1 with no apparent detrimental effect?

Re: May be of interest to Mobil 1 users.
 

#1727 left Marc's shop with Amsoil 10w-40, everything good. For the next oil change I did a blend of Amsoil & Mobil 10w-30...noticeable occasional chain rattle, in addition to finding out additives are reduced now.

I like to do my research one time, find the best recommendation and move on. Been using Mobil1 in everything, but the ZR-1 getting full Amsoil from now on, period.

Re: May be of interest to Mobil 1 users.
 

I use Mobile 1 engine oil in everything else except the ZR-1s just like George :thumbsup:

I use Mobile 1 Oil Filter and Mobile 1 Differential Fluid in the ZR-1s, PERIOD :p

I use Amsoil 10W-40 in the LT5 engine.
I use Castrol 10W-60 in the ZF S6-40 (Black Label or Blue Label) Transmission.

See What Fluids to use in the ZR-1

Re: May be of interest to Mobil 1 users.
 

After doing some research and pondering everyone's input, I think I have decided to go with Marc's recommendation on the Amsoil. After all, he is one who should know.
No more often than we change oil & filters, the cost difference if actually insignificant if it is the best for our cars.
I also suggest we should order from Marc and return all the support he gives to the ZR 1 community.
That's what I am going to do when I do the service on the car this winter.

Re: May be of interest to Mobil 1 users.
 

As good as Amsoil is I have a hard time with the price differential to Mobile 1. I can get M1 for just over $5.15 a quart plus tax. Amsoil is $11.70 a quart plus tax and shipping. Forgetting about the tax and shipping for the moment 10 quarts is $51.50 for M1 and $110.70 for the AMSOIL. I can add a bottle of zinc addative for $10 to the M1, have an even higher zinc level and still be $50 ahead vs AMSOIL on every oil change. With the exception of zinc (zddp) Mobile 1 is still a great product. Unless someone can convince me otherwise I’m staying with M1 even if I have to include the zinc addative.

Re: May be of interest to Mobil 1 users.
 

I believe Pete is using Mobil1 w/o any additives and so far no issues.
I’ve decided on the Mobil1 Extended 10W-40. And now that u mention it,
haven’t noticed much in the way of startup chain rattle.

Re: May be of interest to Mobil 1 users.
 

I pay less than $11 per quart for Amsoil, but I am a preferred customer.. and while I don't pay $5 per quart, I do buy for all my cars.

Where do you guys buy ZDDP from?

Summit... I’ll bet regular auto parts stores carry it too.

Re: May be of interest to Mobil 1 users.
 

I pay $11 a quart for the Amsoil, and I believe I get it from a guy a town over, who is a whole seller....I'm a preferred customer as well. And I notice none to any chain rattle when I have a fresh change...

Re: May be of interest to Mobil 1 users.
 

Being a preferred customer I buy direct from Amsoil.. ~$8 per quart

I buy OE Amsoil for my other cars at ~$5 quart

Wondering if the Z-Rod oil might be better than the AMO for the amount I drive and having to store it each year. cost is a bit better than the AMO for the Z-Rod

Re: May be of interest to Mobil 1 users.
 

Let me start by saying that I am not a chemist.
I too used to add a bit of ZDDP to my Mobil-1.
In a protracted discussion on oil, likely on the Corvette Forum, someone presented a very sound and incontrovertible argument against doing it.
Not enough, and you risk engine damage.
Too Much; You ensure engine damage.
I had used Mobil -1 exclusively since 1976..... but after that day I switched.
I still use Mobil -1 in all of my newer cars, but Mobil deserted our older cars by changing the formulation, so I now have deserted them for the ZR-1 and other non roller cammed engines.


Amsoil certainly has what is needed, and you cannot go wrong with using it. I do on occasion.


However I also use Brad Penn 10w30 Partial Synthetic High Performance Oil. It provides the needed Zinc / Phosphorous and ZDDP.
Brad Penn is the newer name for Kendall GT which I used as a youngster.
It is made in Bradford Pennsylvania at one of the oldest oil wells in the country.
It is also $8.00 a quart.


I no longer buy, use or recommend adding ZDDP unless you have an advanced chemical engineering degree, and proven experience in blending an additive package that does not conflict with it's own ingredients.


Buy Amsoil or Brad Penn and then use your brain for simpler things like world peace or assembling rockets.

Re: May be of interest to Mobil 1 users.
 

Amsoil for me.

Re: May be of interest to Mobil 1 users.
 

This oil discussion thread and discussion of zddp begs the question...

While low zddp levels in modern oil is a known and verified source of cam and flat tapped wear in older design engines, has there ever been a verified case where this happened on an LT5 engine?

I’ve been around the LT5 engine for going on 10 years now and I can’t honestly say I have ever heard of one. Has anyone ever asked Haibeck or Cory Henderson if they have run across one.

Just curious....

Re: May be of interest to Mobil 1 users.
 

Good question Hans. I know of those that don’t add ZDDP w/o apparent consequences.

Re: May be of interest to Mobil 1 users.
 

Re: May be of interest to Mobil 1 users.
 

Jeff,

Marc's comments regarding Mobil1 High Mileage reference the Mobil Oil Chart from 2011. As of 2017, the zinc/phos content is now 800/900 which he states is an unacceptable level.

Re: May be of interest to Mobil 1 users.
 

I read on this forum somewhere that the Mobil 1 High Mileage is better for our car than the Extended Performance. Is this still true?

Re: May be of interest to Mobil 1 users.
 

Certainly a valid argument Marty. But I’m not sure if I buy into it 100%. Zddp additives are now made in dosages designed by the manufacturer to treat certain quantities of oil. Sure you can go crazy and add too much, but that’s the case with anything. While I am certainly not a chemist the question comes down to whether you trust the chemists at the additive company. I doubt these companies would stay in business if their products caused damage when used as prescribed.

This one for example is designed for exactly the situation we are discussing. It is designed to treat 4-5 gallons of regular or synthetic oil and is designed to be added every oil change.

https://www.summitracing.com/nv/parts/isk-zddp

So, sure you can screw things up by not following directions or if you want to play it super safe you can just buy Amsoil (in this case). To each his own I suppose.

Have a great Holiday Marty
