I'm about to make the switch to synthetic and would like opinions on which oil would be easiest to find on a nation wide basis. Does WalMart carry both in their stores across the country?

Any comments on which one is the better quality?

Thanks

Actually, my experience has been synthetic runs cooler. I have noticed some oil burning when using Mobil 1. I've used it in almost every piece of equipment I have over the past 15 years. I decided to try Castrol synthetic and the burning went away while keeping the engine(s) cool. Castrol and Mobil 1 are both available at most WalMart stores.

Mobil 1 is probably the most widely available. Their newest formulation is said to be a significant improvement.

Hi Jim,

Back in the late 70's I bought into the Mobil 1 gimmick on a new Dodge and burnt a case(24qts back then) in a very short time. I never used it again.

I then switched to Pennzoil (dino) and used that until in the mid 90's and the Dodge started using oil again after a oil change. I then changed to Quakerstate and the oil usage went back to normal.

Last year the Dodge once agian started using oil after a oil change. I bought a new F350 so I haven't changed nor drove the Dodge since but I bet it's the Quakerstate as Pennzoil bought Quakerstate in 99.

I put on 225,000 miles on the 76 Dodge with Dino oil and Fram filters. The engine still runs well but the front-end, tranfer case, and body is shot and needs rebuilt.
I also put on 250,000 miles on a 79 T-bird with dino oil and Fram filters. Engine needs rebuilt, body fair, suspension shot.
Both went thru two teenagers! and are one owners!

My point? It didn't matter if I used synthetics or not as the rest of the vechile is shot. I'm glad I didn't waste more money on synthetics over the years.

My vote goes for the Valvoline synthetic! I use it and love it! GM uses it in there oil change bays at the dealships and extends the warrentee to 5000 miles if you tow, 6000 if you dont!

I like Mobil 1 and Valvoline synthetics because of the price to performance. Best is Amsoil, but it cost a lot more.

Have noticed that Mobil 1 has lost some with the reformulation. Doesn't hold up as long. Can tell that my pressure drops sooner and consumption sooner (when I know it's time to change engine oil).

Wally World has 5 qaurt jugs of Mobil 1 and Valvoline synthetic on occasion. They don't do it on regular basis, but do it often. Part of their marketing to get you to go there. Works, as I don't normally go there for auto supplies. Last time I cleared the shelf of 10 jugs. Think they were $16 per 5 quart jug. They also have pretty good normal price on the 1 quart bottles.

Costco carried Mobil 1 for a while, but don't see it there anymore.

Make sure you also use a good filter, as the oil is only as good as the filter and change intervals. I like Purolator PureOne filters and are found at PepBoys.

In any case, there's no problem to switch brands of oil when you do an oil change. I'd prefer to stick with the same brand if I have to add a quart, 'cuz the different brands of oils have different additive packages.

Fram made good filters in those days. They had different owners.

I have also run Mobil 1 for the last 12 years in four small block Chevys. I did not put in the Mobil 1 until I had 6K on each of them. None of them would use a pint between changes solo or towing. I switched to Amsoil for my DMAX. I get it for almost the price of Mobil 1. Autozone carries Mobil 1 also. Later! Lone Eagle

Hope you are right, that the latest reformulation is better than the last reforumation.

Didn't know that Mobil 1 was reformulated about 1.x-2 years ago and noticed that it's performance dropped. Have read that they tried to increase their margin now that they gained good reputation. They have hired some top notched chemist's to do the work this time.
