Read our primer articles on High Mileage Oil, Synthetic Oil and Kinematic Viscosity

For the vehicles in my family I feel I have a proven winner in Redline.

1) 96 Mustang GT
2) 99 Mustang Cobra
3) 86 Corvette
4) 75 Corvette

I also have the 87 Ranger, and my sons's 91 Bronco...These will continue to see whats on sale.

In the 4 listed vehicles I was using Mobil 1 and Mobil EP at the end.. Great oil's on their own, but I always seemed to suffer from burnoff and had to top off.

I also noticed what others have always mentioned, a noisier engine. I have never done a UOA to follow any possible wear patter. Like I mentioned great performing oils but the 2 issues always stuck out at me.

I will stick with the 10W-30, but am considering the 5W-40 flavor for the 75. The HTHS on that oil is 4.6. The viscosity at 100 Deg. C is a whopping 15.1, pour point of -49F. For this 35 y/o Chevy I thinks those are good numbers. Perhaps even add 1 qt. of the 40W redline race oil for an extra dose of moly and zinc.

Since switching over to Redline I no longer suffer from burnoff like I did with Mobil 1, at the most maybe a 1/2 qt per 6k...Maybe...

If anybody has any suggestions or comments I am open to listening to them...Thanks.

Never heard anything bad about the oil. I wouldn't use it myself as it doesn't meet what I want. But...

They have distributors the world over.

They have more than one grade.

If I was to use it, a dealer is only 6 miles away.

If it works for you, stick with it.

6100 Egret Court, Benicia, CA 94510 you can actually see on google satellite.

I actually purchased 2 cases of 10W-30 from racer parts wholesale through Amazon. I believe it worked out to $9.95 QT.

I have about 15-20k in fun money to build a beast. Just going to research things slowly so I buy things only once.

What about the idea of running 5W-40? I mean in the Seattle area we don't see to big extremes of temps...In any case it wouldn't be driven in inclimate conditions anyway. Would that oil provide a level of protection above and beyond the 10W-30? Of course the 5W-40 grade would only be used in the Corvette.

Nice subtle dig by the way. Cool

AD, you are not going to get flamed, at least not from me, then again I am a pretty mellow Bear.

Redline Products are top notch, and Dave, the guy many of us talk too over at Redline is a great guy. I think there oil's will keep an engine cleaner than Amsoil's motor oil's. I believe Amsoil's oil's are kind of old school, some of there oil's do not have Moly in them, and I have noticed my cars run better when I put in some Moly Additive, and Redline Oil's seem to have alot of Moly in them, since Moly is one of the most expensive additives in oil then I can see why Redline's oil's are a bit more expensive. So if Redline seems to be making your engine run better, then you might as well stick with it.

I think when I do my next Gear Oil Change I will be trying Redline Gear Oil instead of purchasing more Amsoil Gear Oil.
Yea I might give their gear oil a shot too. My father was getting me the Amsoil, but the PC fee is a turn off, he used it for a year and decided not to pay for the PC fee anymore.

From all I've been reading I think RL is a better product for the money. But then again that is my opinion, and what is one mans opinion worth? Well my father and uncle feel the same way too, so there's 3 opinions.

AD
Redline's price is about on par with other high end oils. Amazon has the 75w-140 for about 14 a quart now. Not bad, considering RP is about 18 and M-1 about 18 for that viscosity. It really quieted the diff down, especially low speed backing and highway cruise. I have stock exhaust, so I can hear power train noise. But this summer, watch out, Magnaflows are going in!

That's the only bad thing I've heard. Can't quite convince myself to use it, but that takes nothing away from the fact that it's a good oil.
Redline Gear Oil failed 2 basic gear oil tests, foaming and viscosity, according to this white paper http://www.amsoil.com/lit/g2457.pdf .

Does Red Line offer a warranty? I searched "warranty" on their website and found nothing.

This is also not confidence inspiring.
"Q: Will using Red Line products void my vehicle's factory warranty?
Using the appropriate Red Line product shouldn't invalidate your vehicle's warranty and question the mechanic or service manager that says so."

Provided it's the correct viscosity, it will not.
Thanks all for your great feedback...I would also like to point out absent a certain member, we manage to communicate without any drama or attacks.

Since we are on the subject of Redline products...Any feedback concerning the Redline D4 ATF? The Corvette I see as a 1-2 year project...With my job I'm gone a good 8-9 months...The engine/transmission will be replaced with high performance one's. So the Redline products I feel will serve me well.

I am looking forward to enjoying it for a couple more weeks before flying out for a few months...Thsnks all.
Consider lubrication engineers 1150 trans all for the automatics. I buy it in the 5 gallon pails for my automatic trans cars. A very large transmission cooler will make more of a difference than any oil you choose here. Red line MTL for my sons 5 speed focus. Tried red line 75-140 in the mitchel under drive in my f-250. Straight lucas pure synthetic oil stabilizer is much better. Less noise and smoother shifts. I use tractor hydraulic and lucas synthetic 50% each in the f-250 5 speed instead of ATF. Its better in every respect than atf except in very cold weather,and even then it clears up in less than 5 mile of driving. The 5-40 is a little thick for your mustangs. 0-20 or 5-20 redline would be better there. I tried 5-40 delvac in my Lincoln when I was buying it in bulk for my freightliner. Its a little heavy for this engine. That only gets worse if the lucas synthetic additive is used with it. The ford modular engine likes thin oil PERIOD. The small block chevy would probobly be happy with the used oil I take out of my freghtliner after 30000 miles. But if you want to spoil it like a grand child 5- 40 redline will be over kill enough to make you happy.

Another reason I won't be using Amsoil again. For a few $$ anyone can sell it, and it gets old when the reps watch and monitor these threads looking to attack, defend, or sell. That and the $20 fee for the right to a better price, no thanks.

My dads dealer told him if the oil isn't API certified and the suggested grade and there is a problem they have the right to void the warranty. I wouldn't want to be in the middle of that fire fight if my engine checked out because of an oil failure with a non approved oil. Yep this goes for using RL oil too, but I'd take RL over Amsoil for my ride.

Some of these reps will tell you exactly what you want to hear. No RL reps here attacking, defending, or pushing. Sorry guys, but that's how I see it in a lot of these threads, and it gets old man.

For those who have a qualified business, there is no fee to buy at wholesale. By far, most of my customers fall in this category, only 13% pay a membership fee. I only suggest the $10 membership if it saves them more than that on their first order, which it usually does. It also gets them a 32 page wholesale catalog, a monthly subscription to AMSOIL Action News and some other promotional items. And they get 10% off retail after their membership expires. Not a bad deal for $10. And for some tight budgeted college students I know, I have waived the $10 fee.

No manufacturer requires an API certified motor oil, it just needs to meet API specifications. If you don't see the listed vehicle manufacturers API classification listed on a motor oil, then I don't think you should use it. AMSOIL motor oils meet the API specifications, and have never voided a warranty in 38 years. And if the oil ever does fail, you are covered by the AMSOIL warranty.
