Pennzoil Platinum (5 quarts) for $5 Check your local WalMart stores, they're offering a $15 WalMart gift card for every purchase of Pennzoil Platinum Synthetic Motor oil.
Interesting. I've tried Pennzoil synthetic oil before and my fuel economy took a hit for some odd reason - actually, on two cars since I changed their oil on the same day. Both Toyotas, one with a 2.4L I4 and one with a 3.5L V6. Not quite sure what the deal was but it went back to 'normal' after switching to Mobil1 and Valvoline.
For $5 though, it's worth trying again. I'm curious what viscosities are available though?
EDIT: Mail in rebate? Damn, thought it was instant..

Just checked, and no rebate tags attached to the oil at my local Wallyworld.

Thanks OP!!!! In for 6 with 3 different address since limit 2 per household. after we mail, they will send us the gift card within 8 weeks or so.
It is a really good deal. Some WalMart, they did not have the tag or the mail form, so you have to find WalMart that have the oil with the mail form on the cap.

OTOH I tried 100% Valvoline 10W-30 synthetic in my old Nissan, and the front seals started leaking a lot more in a couple of days, so at the next oil change I switched back to conventional 5W-30, and the leaks stopped in a week. Before I tried synthetic, I thought the stories of leaks were just myths.

stop pushing the pedal on the far right all the way down.

I'm just stating my experience. I run all my cars with synthetic @ 5mo/5K mi OCI and have tried most brands at one point or another when they're on sale.
You've got to stop drinking that stuff. There is absolutely no difference between different brands of oil. If you got worse mileage, you must have poured the oil in the wrong hole!!

That's not surprising. When normal oil is used, the seals absorb natural oil and swell filling nicely all the crevices. When you put in synthetic, the seals shrink and gaps form - oil is free to seep through. Only the engines that were running synthetic out of factory should use synthetic.

ABSOLUTELY wrong. - the correct way to state this is that the average user will never see the difference.
I run oil analysis on all my vehicles and can tell you there is in fact a difference, but what I can't tell you is if I will still own the vehicle when the difference becomes apparent. Probably not.
Going to stock up for the wife's minivan, and if it kills it faster - GOOD

Both my Acura Integra and Subaru Outback started leaking/consuming oil in greatly accelerated fashion once switched to Synthetic... had to go back.

Agreed. Very subtle differences between synthetic brands in terms of additive packages, base stock etc as well as tendency to burn/consume tiny bits more or less when abused, but unlikely to be noticeable in terms of capability to lubricate in even harsh conditions for massive numbers of miles.
I usually perform oil changes with the current available cocktail of cheap synthetics picked up off deals over the 7-10K miles since the previous change, ensuring I have at least one quart of Royal Purple or Castrol Syntec (which I think are the best easily available ones, on gut feeling alone ) - the remaining 3-3.5 quarts have been odd mixes of Mobil 1, Castrol, Pennzoil, Vlavoline, Havoline and even Quaker State 4x4 Synthetic in 5W20 and 0W20 weights as available. Engine still pulls like new at 115K miles and (now) 9-12K Oil Change Intervals (OCI). I started out with 5-7K intervals after switching to Synthetic at 1K miles on the odo and gradually grew the OCI based on observed performance, mileage, visible quality and smooth flow. If I could get better oil filters for my 4-banger Mazda, I'd go 15K miles confidently with a 0.5 quart topup, but the paper cartridges look quite twisted to say the least after 10K or so.
Back On Topic - GREAT deal, OP, I'll pick one jug up and split it over the next two OCIs with the Castrol Syntec 5W20 jug I have already. THANKS!

Got 3 jugs. rebate only good for 2 per household. I'll send my son the extra $15. Found it at the Casselberry FL superstore. thanks
Julex said: Both my Acura Integra and Subaru Outback started leaking/consuming oil in greatly accelerated fashion once switched to Synthetic... had to go back.This is a common issue, especially when switching to synthetics on older cars. Synthetic oils are much thinner and therefore seep through gaskets and threadings (especially aged ones) more easily. If you're having trouble with oil seepage, I highly recommend looking at some of the "high mileage" regular dino oils available on the market. They will recondition the seals and gaskets, and are thicker so they don't leak as badly.
Older car seals will often leak after years of using conventional and switching to synthetic. But this shouldn't happen on modern cars--the gaskets are much more robust and forgiving.

This is a great deal, I need to check my WalMart today. Last time I was there they didn't have any Pennzoil products just Castrol, Mobil, Shell, and Vavoline

Gaskets on an old car are old.
Gaskets on a new car are new.
I don't think gasket technology itself has changed dramatically.

Full synthetic has additives to help keep the oil clean. This will dissolve waxes and tars from normal oil that have accumulated in seals. So it's always good to give the engine a good eyeballing when switching from normal to synthetic. Especially, on a high mileage vehicle.
