I've been to every auto parts store/walmart around my house (Morrisville) and can't find a drop of Mobil 1 5W-30. And there are very limited supplies of all the other weights. What's the friggin deal?

Anyone know where I can find some?

The HD Diels 15W-40 products have a High Temperature High Shear (HTHS) rating that is similar to the ACEA A3/B3, A3/B4 and C3 ratings. Plus, the ZDDP has been reduced making it safe for Cats and O2 sensor. Some guys think being a diesel 15W-40 oil is why the cams last longer,becuase it had hgiher ZDDP freaked when it was reduced,but the real difference is the HTHS and similar requirements.

SAE xx rates oil viscosity at 100C/212F

SAE xxW rates oil viscosity at one temperature that is well
below zero but varies depending on the rating (IE: -35)

HTHS rates oil viscosity and shear at 150C/302F

All SAE 0W-30,5W-30,10W-30,0W-40,5W-40 and 10W-40 ratings have the exact same minimum HTHS requirements. (2.9 at 150C/302F) . So a 10W-40 is NOT necessarily any thicker at 150C than a 0W-30.

An SAE 0W-30 that is also ACEA A3/B3, A3/B4 or C3 approved has a minimum HTHS requirement of 3.5 at 150C/302F

So an ACEA A3/B4 approved SAE 0W-30 is actually required to be much thicker at 150C/302F and provide far better HTHS shear protection than an SAE 10W-40 that is not ACEA A3/B4 approved is required to provide. YES, a 0W-30 can be thicker than a 10W-40!!!

SAE 15W-40 has special requirements that exceed the individual "15W" and "40". The include a minimum HTHS of 3.7 at 150C/302F.

Typical SAE 10W-40 and SAE 20W-50 products are discouraged by virtually EVERY OEM and they are not approved by any OEM for use in modern cars. So, many oil companies that make them use their cheapest base stocks in these products and the result is inferior protection when compared to other modern oil products. These 10W-40 and 20W-50 products do NOT share the ZDDP limits that the more common ILSAC approved 5W-30 and 5W-20 products have, but the absence of those strict ZDDP limits in 10W-40 and 20W-50 has not shown any real advantage in camshaft protection (or anything else).

The ACEA A3/B3, A3/B4 or C3 ratings will insure that the oil provides good protection under HTHS conditions. You can find these ratings in the Castrol Syntec 0W-30, Mobil 1 0W-40, Valvoline Synpower 5W-40 and other similar products. These products will be thin enough to allow the flow
required to flush away abrasives and will still provide the required high temperature high sheer protection. I like Rotella.

You will NOT find that approval in Mobil 1 5W-30, Mobil 1 10W-30, Mobil 1 0W-30, Castrol Syntec 5W-30, Valvoline Synpower 5W-30 or other seemingly similar products. These are NOT the correct oil products for with flat tappet lifters.

BRAND MEANS NOTHING!!!!!!!! If you turn the bottle over and it does not say that it is ACEA A3/B3 (or A3/B4, or C3) approved, then it does NOT meet that approval!

So, using Mobil 1 is NOT the answer, using Castrol Syntec is NOT the answer, and using Valvoline Synpower is NOT the answer. Only certain products within those lines (and others) meet the requirements.

Anything that has ANY of the following approvals will NOT meet the requirements you need to protect the 1960s Tech, flat tappet lifters engine that Land Rover Used:

ACEA A1/B1, A5/B5, C1, C2 GM 6094M, 4718M ILSAC GF-4

The choice is yours. I like Rotella.

where in the hell did you find that copy/paste bullshit from?

12/6/2008 10:12:52 PM

lol

12/6/2008 10:23:57 PM

same place i get my joints from, y0...

^^^did you stockpile rotella? you did, didn't you, you son of a bitch! i liked rotella for the diesels, but never ran it past a break in on a gasser.

Zinc dialkyldithiophosphate (or ZDDP)...bet you fuckers don't even know what the fuck it is...and how you can supplement it EASILY.

Extreme pressure lubricant that intervenes under would-be scuffing conditions...high-temperature, high pressure, high shear. The shit does nothing under conditions in which an adequate oil film is maintained under pressure. but it's of benefit in flat-tappet engines just for the reason above. Most newer engines have roller tappets or roller cam followers, and it's not as critical.

Levels have been lowered because of emissions standards and worries over phosphate content. But here's something for you...fucking plain old STP and a lot of the no-smoke-worn-out engine oil additives that are thick as snot have it in them. Ever buy engine assembly lube? The red shit made by Federal Mogul (and often sold under the trademark name Snake Oil) has it in it.

By the way, I did not cut and paste any of this shit. I've been in auto parts sales for more years than a lot of folks go to school. BLAH. So there.

If it aint Warren it aint oil

12/7/2008 1:44:03 PM

just buy some CH-4 rated oil (if you can find it) and stay away from the new CJ-4 if you're that worried about it.

12/7/2008 2:53:38 PM

national shortage of Mobil 1 5w-30. My store (Advance Auto) hasn't had it for awhile now.

12/7/2008 7:52:02 PM

I noticed this as well, but it took about 2 seconds of pondering before I bought 10w30 instead. Something tells me you'll be fine if you do the same.

12/7/2008 9:06:13 PM

My oil is just passing through, so it doesn't matter what type I use.

"PAO Shortage Squeezes Mobil 1 By George Gill The continued shutdown of the ExxonMobil Chemical polyalphaolefin (PAO) plant in Beaumont, Texas, has forced ExxonMobil Lubricants and Specialties to institute a sales allocation on a variety of Mobil 1 synthetic lubricants, effective Oct. 1. “On Sept. 15, ExxonMobil Lubricants and Specialties was notified by our primary polyalphaolefin supplier, ExxonMobil Chemical, that Hurricane Ike had caused significant disruption to production capabilities at their Beaumont, Texas, plant, and to the ability of their suppliers to make deliveries of critical raw materials and services to the site,” the company told customers in a letter obtained by Lube Report. As a result, ExxonMobil Chemical implemented an allocation on sales of PAO base stocks to customers including ExxonMobil itself. “This allocation is expected to last several months,” the letter stated. According to Lubes’n’Greases magazine, the Beaumont facility is one of the world’s largest PAO plants, with capacity to make 82,000 metric tons per year. ExxonMobil spokesman Kevin Allexon confirmed yesterday that the PAO plant remains shut down due to the hurricane damage. “We have folks working on the repairs, we’re making good progress, but there’s no timetable for how much longer it will be,” Allexon told Lube Report. According to the advisory letter, customer liftings are restricted to 100 percent of prior purchases on products such as Mobil 1 SAE 0W-40, 5W-40 and 15W-50 engine oils; on Delvac Synthetic ATF; Mobil 1 High Mileage 10W-30 and 10W-40; and Extended Performance 5W-20, 10W-30 and 15W-50 motor oils. Also at 100 percent allocation is Mobil 1 ESP 5W-30. There is a 65 percent allocation on the brand’s SAE 10W-30, and the allocations drop even further for Mobil 1 0W-20, 0W-30 and 5W-20 oils, to 25 percent. Truck and SUV 5W-30 is also at 25 percent allocation. The tightest allocations are those in force for Mobil 1 5W-30 (20 percent) and EP 5W-30 (15 percent). In the letter, ExxonMobil explains that a product on 100 percent allocation means a customer can continue to purchase it at the customer’s average 2008 purchase levels. Volumes for the allocation are based on a customer's average monthly purchases from January to August 2008. A Midwestern distributor that buys several truckloads of Mobil 1 synthetics a year said it had seen a lengthy delay in receiving shipments. “We placed orders back in late July and August, and we were told if we were lucky, we might see it in December,” the source told Lube Report. “It’s affecting our customers. The good thing for us is we do have other alternative brands. Somebody who's just a Mobil guy can run into problems when they don't have any synthetic alternatives.” A Southern distributor said the PAO shortage in the market in general is impacting more than just Mobil 1. “With PAOs in general, that supply was messed up before Ike – all that did was further mess it up,” this source said. “The PAO shortage is not just confined to Mobil 1, it’s confined also to any kind of industrial oil that’s made with PAOs.” "

couldn't you just use 10W-30 instead of 5W-30 living NC?

12/9/2008 3:06:28 AM

technically yes.

12/9/2008 8:25:38 PM

its all going into our industrial lubricants, cause we will pay 2-3 times more for it

12/11/2008 6:48:27 PM

went to Walmart yesterday, and couldn't find any Mobil 1.

1/7/2009 7:52:10 AM

seems like autozone still has good stocks

1/7/2009 7:54:50 AM
