Most of you aren't as cheap as I am but in case you are interested Autozone has a $2 off per quart on VR-1.

i'm as cheap as you are, but i still use mobil one. autozone does a special, 5.5qt jug and a mobile one oil filter for $35.00. trust me, thats cheap. besides, i can go 10,000 miles instead of 3,000 miles between oil and filter changes. plus the benifits of great engine wear protection.

...i still use mobil one...

Not a Mobile1 fan - had an issue with it several years ago in a Pontiac and have never given it a second try.

i'm curious, what was the issue? i've had incredible success with it. it even saved the engine in my F150 once.

Lifters would raise hell when things got hot (well hot in Virginia standards) - simple change back to dino and they would quite back down and the car would run great.

Perfer VR-1 over Mobil 1, not enough zinc in Mobile 1 for my cam. I've only destroyed one engine in my lifetime and that engine had Mobile 1used exclusively in it.

Can't say for sure Mobil 1 caused it, just don't have a warm fuzzy using it now.

New stuff gets Mobil 1 and old stuff gets Castrol GTX 20-50 w/pint of Marvel Mystery Oil.

I too always think I have to add a can of something with my oil???
I use Zmax and it seems to let the engine turn over faster to start.
My oil of choice has always been Castro something or other.

If you ordered a 4th Gen Camaro optioned as a SS, it came from SLP with Mobile 1. On both SS Camaro's that I owned, the lifters ticked annoyingly loud. After doing research, it seemed to be a common problem with the LS1 lifters. Changing from Mobile 1 to Royal Purple not only eliminated my issue, but it also gained me 2-3 miles to the gallon.

Since then, I've never given Mobile 1 another shot and have been a loyal Royal Purple user. In fact, last summer coming back from Birmingham the thermostat in Jade stuck and the engine got so hot that the entire valve train started to rattle. I was cruising at about 70 MPH and I lost ALL oil pressure. I was convinced that the engine was about to come apart because as I feathered the gas pedal trying to isolate the issues, the engine just kept getting hotter and hotter. After about a mile or so, which to me seemed like an hour, Jade went from cruising at 70 to barely running. Once I finally made it to the shoulder of the road, I popped the hood to find my radiator flexing like a heartbeat. My upper radiator hose looked like a python that just swallowed a cow whole, and oil was literally leaking from my head gaskets. You could smell burnt oil everywhere and it was so hot that the rubber from my K&N oil breathers in the valve covers were burnt and toast.

I was 100% convinced that I broke something or did internal damage from the car getting that hot and breaking the oil down but believe it or not, all I did was flush the engine, pour 7 fresh quarts of Royal Purple XPR in her, and a year later she's still running like a champ!! It was so bad that I took pictures, documented everything and then sent it in to the technicians at Royal Purple thanking them that their oil withstood that kind of heat and abuse.

After that, I installed a temperature gauge that actually worked...... Ha Ha Ha!!!

this is the true advantage of the synthetic in the syn/dino debate. Heat and oil breakdown. I do know several people whose engines were saved by synthetics. i am just an old man set in almost 50 years of Castrol/Marvel Mystery Oil ways that don't need change. BTW adding MMO to my system isn't just a thought......when you pull my valve covers and see my 50 year old new looking valve train, and drop the oil pan and ask if it's new, will explain the whys of it. before fuel injection, i used to put it in my gas tank as a top cylider lubricant that actually helped with dry starts and ring wear(ridge) in the cylinder walls..

Alan......how did we get here from trying to save $2?

I have used Castrol GTX & Marvel Mystery Oil for over 40 years..... Now with my new Ram SRT-10 my boys want me to use synthetic in it..... Moble1 was there recommendation but I am so old school I have not decided yet.... Need to change it soon....

I use Royal Purple HPS (High Performance Street) oil in the Vette and the Camaro. It has Zinc and Phosphate added. The engines run cooler and the mpg in both cars increased. Yes, it is expensive. You can get it for around $10.50 a quart and in my opinion it is well worth every penny.

I run valvoline Vr-1 in all my junk, it is what my builder recommends, if its good enuff for his 2400 hp turbo car , its good enuff for me!

there's as many opinions as there are car guys. there's probably no one right answer. but with me, with Mobil One, for all the same reasons...better gas milage, cooler running engine, more horsepower, longer time between oil changes, and i have seen how clean the inside of my engine looks after 93,000 miles. my daily driver Escape has 154,000 miles on it (shoot, i shouldn't have jinxed myself. damn it)

sorry guys - in the future I will try harder to not share this type of info
