I beleive all the hype. If it's so great why wait for the super bowl.

Right.
Because at $3 million for 30 seconds, you might as well get everyone you can to watch.
I'd try it as long as it meets or exceeds gm specs. I use castrol in my other vehicles.

To think all these years using M1 without a single issue... man .. am I lucky or what!

Here we go again another chimp has wondered into the compound and is going to try and steal a banana or two from the BIG GORILLA on the block !

That's BIG GAME please, as the SB is copyrighted and and can't be used without paying a fee to the NFL.

I won't put Castrol in my lawnmower.

As long as it meets GM4718M.......

Never Say Never

If it's so great, why doesn't GM put it in new corvettes instead of Mobil 1?

Another vote for needing to meet GM specs. It also needs to be price competitive. I'm interested to hear how they arrived at the "8X." An independent test would be nice too.

PROBLEM! PROBLEM!

Under the Castrol USA website, entering the word "Edge" since there is no reference to it, gets the following.

I've highlighted the Castrol website's 5W-30 paragraph below:


Grades
Available Grades

Castrol SYNTEC Bottle close-up

SAE 5W–20:
Castrol SYNTEC is the first major full synthetic oil brand to offer a 5W–20 that is specifically formulated to meet the needs of Ford, Chrysler, Honda and Toyota 5W–20 service.

SYNTEC 0W-20 is a full synthetic oil that helps extend engine life while delivering maximum fuel economy. SYNTEC 0W-20 is suitable for newer Toyota, Honda, Chrysler and Mercury models. Because of its low viscosity, SYNTEC 0W-20 provides excellent protection in low temperatures. API service SM. SYNTEC 0W-20 meets catalyst/emissions system compatibility and all requirements of ILSAC GF-4/GF-3/GF-2.

SAE 0W–30:
Castrol SYNTEC 0W–30 European Formula is engineered to meet the Mercedes Benz 229.5 specification. The 0W–30 viscosity grade is ideal for winter conditions where low temperature pumpability is required. A unique, low–temperature formulation provides exceptional pumpability in cold weather and allows for unaided engine starts down to –40ºF. Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SL, SJ, SH, CF or CD is recommended. Exceeds European ACEA: A3, B3, B4; VW 502 00, 505 00, 503 01; MB 229.1, 229.3, 229.5; BMW LL–01; GM–LLA–025, GM–LL–B–025 and the engine protection requirements of ILSAC GF–3 for API Certified Gasoline Engine Oils.

SAE 5W–30:
is the most recommended grade in today's new cars. Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SM, SL, SJ, SH, CF or CD is recommended. Exceeds European ACEA: A1, A5, B1, B5, GM 6094M; Ford WSS M2C929–A and all requirements of ILSAC GF–4 for API Certified Gasoline Engine Oils and meets Energy Conserving Standards. In extreme tests, Castrol SYNTEC 5W-30 maintains maximum horsepower longer than the leading conventional oil.

Note: it is possible this oil is so new that there are no tech specs for it. but, the ireland castrol site only lists Edge as 0W, and it's not GM4718M specced.

I sold a Pontiac Bonneville with 190,000 miles on it and it still didn't use oil. It was the old Buick V6. That said I don't have a problem with Mobil 1 wear. I did; however, rotate a bearing on my '99 Blazer 4.3 V6 using 40% Mobil 1. I have heard of 4.3 troubles before so I don't blame the oil. I would guess one can google this new oil for quantitative tests to be published. If they don't show up (ever) then it is hype of course.

Curtis A. Franz

Okay I googled "castrol edge" and from a non-castrol site I found the claim that it does meet the Corvette spec as 5W-30.

Castrol EDGE is an advanced, proprietary formula that provides performance and protection in extreme conditions such as towing, hauling, high and low tempuratures, rapid acceleration, and stop-and-go traffic.

Guaranteed extended drain interval protection for 15,000 miles, or one year, whichever comes first. Performance and protection that outperforms conventional, high mileage and synthetic blend motor oils.

Castrol SYNTEC is not a full synthetic........I will never again use a Castrol product in anything that I own......for years, I purchased and they sold their SYNTEC as a full synthetic............it is mineral oil based, folks, and they change one little thing in the OIL's formulation and call it synthetic..........do the research on this:

I felt betrayed by Castrol when I found this out, and swore to never use their products (or trust their advertising claims) ever again!!

Never Say Never

Castrol a joke. They should of received some heavy fines for that.

danl72

Same here.

Thanks for the validation on this..........I try to be positive (or not be TOO negative) here on the forum....but I still have my bad feelings about Castrol's deceptive practices and definitions of "synthetic"...as you can probably tell!!!

cclive

I like Castrol, but the oil must meet 4718m...
