The New API SP Formula is better suited for the Direct Injection Engines that are Euro Spec'd.

🧪 1. Starting Material
Some synthetics start with crude oil, like conventional oil — but they heavily modify it.
Others are made from chemical building blocks like natural gas or specially created molecules (this is called gas-to-liquid or chemical synthesis).
2.
They take the raw material and break it apart at the molecular level.
The goal is to remove all the bad stuff — like waxes, impurities, uneven molecules.
They rebuild it into smaller, consistent, super-smooth molecules.
➔ Think of it like smashing random Lego sets apart, and then rebuilding a perfect, strong spaceship from only the best pieces.
🏗️ 3. Building the Perfect Oil
The resulting molecules are:
Uniform in size and shape (this helps them flow better).
More stable at extreme temperatures (they don't burn off as easily in heat or thicken in cold).
Naturally cleaner, helping prevent engine sludge.
Additives (like anti-wear agents, detergents, corrosion inhibitors) are blended in to boost performance even more.
🌎 Types of Synthetic Oil Creation:
Group III Synthetics (Highly refined crude oil — technically "synthetic" under U.S. labeling rules)
Group IV Synthetics (True chemical-built oils, often made from polyalphaolefins, or PAOs)
Group V Synthetics (Speciality bases like esters, used in extreme-performance oils)
⚙️ Summary in Plain English:
Synthetic oil is like a custom-designed engine lube made from the best, most durable molecules, while conventional oil is just a cleaned-up version of nature's random mix.

Which are true synthetic brands/products?
ChatGPT said:
🏆 "True Synthetic" Oils (Group IV PAO-based or Group V ester-based — built from scratch molecules):
Brand / Product LineNotesMobil 1Especially their mainline Mobil 1 Advanced Full Synthetic — one of the purest PAO synthetics still widely available.
Amsoil Signature SeriesTrue synthetic, ultra-premium. Built for extreme performance.
Royal Purple High-Performance SyntheticHigh-end synthetic with a strong ester base (Group V influence).
Red Line SyntheticVERY high ester content (true Group V synthetic), used heavily in motorsports.
Liqui Moly Synthoil SeriesGerman brand, real synthetics — very strict European standards.
Motul 300V and Specific seriesHigh-end racing and specialty synthetics, heavily ester-based.
Pennzoil Ultra Platinum (Shell GTL base oil)Made from natural gas via a gas-to-liquid (GTL) process — extremely pure, better than crude-based synthetics.
⚡ Brands that are good but mostly "Group III" (very refined crude, not truly built-from-scratch synthetics):
(Still great oils! But technically not "true" synthetic in old-school terms.)
Castrol EDGE (most formulas)
Valvoline Advanced Full Synthetic
Quaker State Ultimate Durability
Kirkland Full Synthetic (Costco brand — great value, but Group III)
🔥 Quick Way to Spot It:
If it says "Made from natural gas" (like Pennzoil Platinum) → very pure.
If it mentions PAO or Ester Base Oils → true synthetic.
If it's just "full synthetic" with no details → likely Group III highly refined crude.
Bottom line:
If you want absolute top-tier "true synthetic" oil, stick to Mobil 1, Amsoil, Red Line, or Royal Purple.
If you want awesome protection for less, Pennzoil Platinum and Castrol EDGE are still very good choices.
I couldn't find the specification about its compatible with bmw long life 01.
Any link/reference?
walmart also has 3pack for $75
WTF it's on the front page???

Note: UPC 071924150157 corresponds to the old API SN formula.
This UPC is associated with the older Kirkland Signature 0W-20 full synthetic motor oil, which uses the API SN (not the newer SP) certification. It's been largely replaced on shelves by an updated formula with API SP for better wear protection and LSPI resistance.
