It seems we old school guys are now getting synthetic oil rammed down our throats one way or the other. I have been to two stores now that quit carrying fossil oil in favor of synthetic. I am not starting a debate here just wondering if this trend is local or everywhere. I only use fossil oil and don't care for the synthetic. Kind of like states that only have 10% ethanol fuel where you don't have a choice.
 
Synthetic in everything I own. Superior lubrication.
 
Personally I believe it costs 3 time as much to do the same job. Of coarse to each there own. I just like having a choice in the matter. Like I said not debating one over the other.
 
Oil is always a debate. Even at $10 a quart, it’s the cheapest insurance available.
 
If everyone would do oil samples you would find out how good the sun oil is. But it costs a few bucks but again after spending 10 gs up to whatever your wallet can handle for your engine build a few bucks won't hurt.
 
I believe running synthetic in the older original engines, is not the way to go. The build tolerances were nothing like they are now. I prefer to run conventional in my "antiques", with a Zinc additive, but I am working on a "new" stroker for my '63, and will be running Mobil 1 in that, under the advice of my builder...

Well with tolerances like that I'd invest in a shop rag company:D

Kidding aside, I haven't seen much of a downturn in the availability of dino-oil, at least around here. It wouldn't surprise me though, considering all the newer stuff runs synth from the factory. High-zinc dino is another story as we all know.... for gas engines the only staff I see at the auto parts stores is the VR1, and that's even only at O'Reilly's.
 
Running flat tappets I'm useing zddp. I used the Penn Grade break in oil then after 500 miles went to their 10w 30w partial synthetic.

The Mobil 1 has a ZDDP level of 1000 ppm
 
It comes down to the components in the engine, and what it's used for. The quality synthetics have slightly better cold flow performance and higher safe operating temps. But it's really important to use the correct viscosity based on the clearances and materials used. And if the oil does not have enough ZDDP, it doesn't matter what you use. I like synthetics. Amsoil and Gibbs Driven. Change it often and I use Wix filters.
 
Lately I have been shopping on Amazon for my oil needs. Free shipping to your door if you buy enough and pricing that beats the auto parts stores and large variety. Filters aren't much different in price though.

I change oil once a year, filter twice. I've always done that.. I put on maybe 1000/1300 miles a year, so the expense of synthetic once a year, why not. It's that zinc thing that makes me wonder about the waste of money. If you have a solid lifter engine or breaking in any engine I would use it. Reading some articles by knowledgeable people, zinc is really not needed otherwise.
 
I still use conventional and have no trouble finding it. Walmart Supertech is conventional, good price and a good quality oil. I use that in my daily drivers, Rotella T5 in my Road Runner, but I think they say that is a "synthetic blend".

P.S.
I do add a bottle of ZPPD plus to the Rotella.

All flat tappet cams need either a zinc oil, or at least a zinc additive. Your last sentence shows how little of a grasp on how important zinc is in a flat tappet cam engine.
 
I think you know little about reading, bee .. read the post again ( solid lifter engine) .. and why the attitude ?

You seem to be one with the reading comprehension issue. I said "Flat Tappet Cams". This covers both solid AND hydraulic. Zinc is required due to the extreme pressure (EP) requirements between cams and lifters.
 
If this is a conspiracy, they’d better lower the price. And make that fossil based stuff available goddamit.
