Has anyone tried Mobil dino oil? I'm currently using Castrol and curious if non-synthetic Mobil is any good. Afterall, it's 40 cents cheaper per quart.

It's probably okay, although personally I think synthetic is about 1,000 times better than any dyno-based blend. There are numerous reports / studies on this.

It's be good not better then synthetic oils but good. Also most dino based oils are now a synthetic blend.

Which oil is best? Now there's a can of worms! I've come to the conclusion it's ones preference.Dino or syn.? Again, to each his own. Ive gotten a lot of info from Bob is the oil guy .com.,And an ongoing debate on offshoreonly.com. (a boating site) Just a tip.

Btw, I figured out Mobil's little marketing scheme. The 15,000 oil is their original mobil 1 synthetic, 7500 is the blend, and the 5000 is just their old mobil "drive clean" dino oil.

I was curious if anyone has tried the latter and could compare it to other dino oils. Thanks.

Mobil is a good oil. I used to run it in everything. Its better then castrol. Mobil stays cleaner longer. Its just my opnion, but that is what I have expierenced first hand.

I had no idea Mobil ever made dino oil. Up here all we get is Mobil 1.

at 17.75 for 5 quarts of Mobil 1- and 2$ for gas... (Ok in Cinci today 2.29 for premium) use better oil. Less friction will save you on fuel costs. I guess I'm cheap.

For street use they are all the same.

Oh, so the fact that Quaker State has teflon in it has no significance? Trust me, there is some difference between dino oils. I was just simply curious if someone had past experience with it. Thank you.

Upon further investigation...mobil discontinued 15-50 "mobil 1."

The only 15-50 oil offered by mobil is "mobil 1 extended performance," which costs ~5.50 a quart!

Lame. Back to castrol gtx...

Wait, quaker state has teflon in it?
Bad idea...
I remember reading the summary of a study, stating that teflon molecules are too large, and when they heat up, and become larger than a lot of clearances in an engine or something like that, which will actually lead to increased engine wear?...
