I find this great in winter for easy starts in cold weather. I also go 6-7,000 miles between oil changes. Use Mobil 1 now but hear Amsoil is better.
Any comments on synthetics?

Any of the premium synthetics will be an excellent choice. I use Amsoil in my daily drivers for the past 15 years.

Synthetics are good for extreme cold starts and newer engines. Older and high mileage cars have more tolerance in the oil rings so dino oils are more economical. The choice to use synthetics is mainly dependent on your history of purchasing cars. If you change vehicles every 5 or six years, doesn't make sense to spend extra on synthetics. If you drive an oil burner, doesn't make sense to use synthetics. If you live in a warm climate, doesn't make sense to use synthetics. Trying to extend the length between oil changes should not dictate your choice in buying synthetics. The longer you go without changing, the more acids build up in the oil. Also the lubricating qualities breakdown over time and by the heat. Longer intervals may save you some money but the contaminates circulate more often the longer you go. I drive a diesel and diesel drivers check oil chemistries pretty frequently.

I have been using Amsoil for many years and I go 10,000 between oil changes. The car (2004 Mazda 6, 2.3L, 5 speed) has 188,000+ miles, still runs great and doesn't burn any oil. I am expecting at least 250,000 miles or more before purchasing a replacement.

I've been using synthetic for twenty years and love it. Oxidation point is much higher than conventional (great for old air cooled bikes) and allows a longer interval on changes.

I replaced my old Honda Civic with a new 2013 Mazda. Looking the owner's manual for it and other rental vehicles, I see that manufacturers now almost all recommend 0-20 weight synthetic oil.

0-20W Pennzoil Platinum synthetic oil - 0-20W required by Toyota warrantee for most of their new cars. They are recommending 8000 between oil changes.
It is supposed to increase gas mileage.

Cars are kept in a semi-heated garage so 10-W40 would probably turn it over just as quick.

I always use synthetics. The cost is worth it if you change your own oil. Otherwise it can get expensive.

I've been using full synthetic since 2005. I use Mobil 1 0W-40. It's API SL, SM, SN. It's ACEA A3/B3, A3/B4. These are all rare combinations. It's also BMW Longlife 01, Mercedes Benz 229.5. It used to be GM-LL-A-025 but now GM has a more lax Dexos standard, which it is.

I wonder if I drink a Gallon a day If I'd be extremely healthy or
just extremely broke??

Something I read....
Excerpt From Blackstone Labs.

What's the best oil to use?

Ah, the million dollar question. We are an independent lab, so we don't make recommendations. It has been our experience that oil is oil, and either petroleum or synthetic-based oil will work well for just about any engine.

Grumpycat, what specs am I looking for in an oil (and especially a synthetic)?

In my case, it's for an 09 Sienna V-6. The only spec in the owner's manual is 5W-30.

Shopping for "synthetic" is misguided.

Shop for performance specifications, not marketing buzzwords. Use of synthetic manufacturing techniques does not automatically give a motor oil the magic properties which some synthetic motor oils posses.

Doesn't matter, Group IV, V, VI, ester, PAO, etc. Those are techniques, not performance specifications.

To all of you who think they are saving money using petroleum oil and changing it more frequently – you are actually spending more money each year than anyone who uses a high-end synthetic and gets to change their oil twice or only three times a year. Do some homework on synthetic oil. There are four types. Some have great viscosity and wear ratings when they first poured in your car, yet drop off significantly before you have driven 3,000K (see Royal Purple). Others, like Amsoil or Red Line, with the proper filtration (emphasis mine), can last six months to a year depending on severity of miles driven. It is also worth the $25-30 for an oil analysis. The test will tell you whether you need to change your oil or if you have other issues concerning higher than ordinary wear levels occurring in your engine.

use Amsoil full synthetic oils and filters in both vehicles. No issues. Its cost's a little more than other oils, but I think it is worth it.
