New Motorcraft 10w30...outstanding minoil

TBN 6.50


Motorcraft has re-formulated its 10w30, and appears to be using the same outstanding Conoco technology that has made their 5w20 a believer out of me, where I was a skeptic. The new MC 10w30 is identified by the wording of "hydrocracked/synthetic" in the language on the back. Considering this oil can be bought at Wal-Mart for $15/case, it is an outstanidng deal, and a top choice for you frequent oil changers. The TBN actually is a bit higher, so this oil is a 4-5K change oil in the S2K, 3K easy.

How do you get all this info? AND many thanks that you share it with us!

too much info.

i'm just gonna keep using amsoil 10w30...road rages ORIGINAL recommendation.

How does this compare with the Castrol GTX Drive Hard (min) oil? From reading your oil comparison thread, it seems that for the mineral oils, the Castrol GTX seems to be the best choice, unless I misinterpreted the information.

How does this Motorcraft compare? I know that Motorcraft is mostly used in Ford's, so I never really considered it for the S2000... currently, I'm still searching for the best mineral oil to use (for some reason I just don't think its necessary to spend the extra money on synthetic oil, for a motor that is essentially stock).

My car is used for daily driving in addition to spirited weekend driving on backroads and the occasional auto-x.... I do drive the car alot though. I drive roughly 400 miles a week.

I have not changed the oil myself (for its 20k mile life, it has only seen Honda oil, which I hear is Mobil Drive Clean), but I intend to change oil myself, just because I know it will be done correctly. Plus I don't exactly trust the fact that Honda likes putting 0w20 and 5w20 oil in the car.

"How do you get all this info? AND many thanks that you share it with us!"

I read what I am sent, and have good recall. I also work hard to keep up with new developments.

jyeung: Sorry, man, for the brain drain But life moves pretty fast - things change.

You guys want me to retire?

Castrol GTX is OK - I think MC's product is better. The base stocks are similar to what Syntec uses. And just because it is marketed by Ford, do not cut yourself short and be biased against the product. Ford of course outsources development of their lubricants to major oil companies, including Conoco.

And I believe Foprd makes some fairly quick cars - can you say SVT Cobra and Ford GT?

Thanks for the info Glenn.

Mind replying to my post about Valvoline Maxlife also? I'm undecided whether to use MC plain, MC with Maxlife engine protector, or just the Valvoline Maxlife oil itself, so your response to my other post may clear some things up for me and aid in me making a more informed decision.

What about the 5W20 thing? Would you (RR) use 5W20 in an S2000? Do you think that MC 10W30 would be a better choice than Mobil 1 10W30?

I was browsing the Motorcraft website and saw that they also have a synthetic MTF and a friction modifer additve. Do you have any information on these? Also, there is more than one 10w30...even some synthetic blends...which one are you referring to?

Thanks for the great information.

RR's threads are all good reads... gets kinda confusing but glad you're here! :thunbsup:

BTW I still have a case of Amsoil 10W-30 left... kinda off topic but how often do you recommend a change? They say like 12,500 miles for high performance cars but ehhh I dont think it'll last that long

yeah I also run amsoil 10w-30, but Im scared to leave it in that long. I have tried in the past to leave oil in for as long as the factory recommends.. and I just cant do it. I hate to see black paint draining out of a car or truck I paid so much for. my s2k's oil will get dark at about 2k, and at 3k it comes out.

Hey gang,

For how to get this info and anything else you ever wanted to know about oils, check out the forums at www.bobistheoilguy.com

Road Rage, is this Motorcraft non-synthetic?

If it is, wouldn't it be better to stick with Amsoil since Amsoil is synthetic?

You really need to do some research on oil. You're changing out and wasting a perfectly fine synthetic at 3,000 miles.

Silly Rabbit, read the oil journals!

To be fair, the Motorcraft is not a true synthetic, but rather a hydrocracked dino oil. Some manufacturers are labeling these as synthetics, even though they have a conventional base.

Royal Purple!

RoadRage is simply saying that if one was to go with a mineral oil (conventional dino), that this is a good choice to go with.

If you are using Amsoil, by all means keep using it. It is one of the best synthetic motor oils on the market... this Motorcraft stuff is just another alternative for those deciding between Castrol GTX, Valvoline, Honda (Mobil DriveClean), etc... but since you are using a synthetic, no reason for you to digress in lubrication technology.

Black is good, it means its absorbing carbon and other impurities, among other things... this is what you want it to do.

Amsoil is one of those extended life type of oils where you can go longer between oil change intervals. You can go at least twice as long between oil changes... don't change simply because it is black...

oakfloor- you need to get an oil analysis done to see if your oil really needed to be changed. You really can't tell just by looking at the colour!

thanks for all the info, yes Im a waster of good oil. Im gonna leave it in longer this time and replace the oil filter at about half way thru. but I do recycle it. So where can I get a UOA done?

guys

I have looked for this stuff at three Wal-marts and i don't think they carry this oil anymore - I also called a local ford dealership and the guy was clueless

I ended up picking up some penzoil for this change BUT where do you find the motorcraft stuff

Thanks

RoadRage had a new favorite mineral oil: "The new Havoline GF-4 formulations"

Yes, that's about right. We have tested both the 5w20 and 10w30's, and they have about the same chemistry, with outstanding base stocks, amines, and plenty of moly - 400-500 ppm, about the same as Red Line. They are as good or better than the MC's at least up to 5000 miles, and above Arctic temps. I just bought a case of the Havoline GF-4 10w30, and may never go syn in my car (it only has 2200 miles on it in nearly 2 years).

Road Rage what are your thoughts on time as a factor for oil changes?

Everyone seems to be more concerned about mileage on oil, but what if the S is rarely driven? I'll bet some people put only 2000 miles a year on their car... does that mean they can go for 2.5 years (5000 miles) without changing their oil?

I've always heard every 3 months to change it... due to moisture and impurities entering the oil over time. I won't get 5k miles (I use Mobil 10w-30 synthetic) in 3 months but I still change it in that time.

Even Mobil 1 synthetic costs less than a full tank of gas right now... so it's not a huge expense.

RR has stated in previous posts that he changes his oil once a year or 12k miles in the cars that he uses Amsoil in, with a filter change in the middle (6k or 6 months). That's the advantage of high grade synthetics, less frequent oil changes. I just changed out my Amsoil with about 6k miles on it and will be sending it in for a UOA.

Thanks and Thanks to RR for his recommendation
