Red Line, Royal Purple or Amsoil?

[LexAtlanta]

I have used all three of these off and on for years. I am currently running Red Line 5w30 in the motor of my 2001 Tahoe. I also have Amsoil ATF in the 4L60E and Royal Purple in the rear end. We just bought a new 2007 Nissan Quest and I would like to pick an oil and stick with it.

Which oil do you guys think is the best? I want to use the Amsoil ATF in the transmission of the Nissan, but I am torn with what to use in the motor. I like all three equally and think that the quality of each is about the same. Red Line is the most expensive at about $9 per quart.

Any input would be great.

Of those three...I would go Amsoil front to back.

 

[Johnny]

Sarge and I are in 100% agreement here.

 

[LexAtlanta]

OK...but would you run the 0W-20 or the 5W-20 in the new van. Also, should I wait until I get 7,500 miles on it to switch to full syn? Or do I do it at the first oil change?

Lastly, why do you think Amsoil is the best of the three?

 

[sprintman]

Redline for sure

 

[buster]

Amsoil all the way. They are making the best oils right now IMO.

Maybe Red Line or Royal Purple if you are going to be racing. Amsoil for normal use.

Why?
1. Amsoil has been around since 1972 and was the first in API certified synthetics.
2. Amsoil is the only one that has a free parts and labor warranty for extended oil change intervals should the oil fail.
3. Amsoil openly compares their products against the others by name. I know they compare the 10W40 motorcycle oils in their 26 oil comparison with 10 ASTM tests. Amsoil finished #1 out of 12. Royal Purple was #7. I think the car oils would use similar base oils and additives.

Change out to synthetic at first oil change. Amsoil says the sooner the better.

Amsoil lists these oils for your Quest:
Engine Oil
Grade 1......API*
Series 2000 Synthetic 0w30 Motor Oil
SAE 5w30 Synthetic Motor Oil
SAE 5w30 XL Synthetic Motor Oil
Above 0°F......10W-30, 10W-40
All Temps......5w30[1]
1. SAE 5w30 is preferred.
Not sure I'd run a 20 weight oil if not recommended by Nissan or Amsoil. Does your owners manual say something different?
Of these 3 listed, I'd run the 0W30 for best gas mileage and longest oil change intervals.

Also get these filters when you are ready to change:
Oil Filter........ EAO12 AMSOIL Ea Oil Filter
Air Filter........ EAA74 AMSOIL Ea Air Filter

Another vote for Amsoil here. After two short OCIs I would probably stick with an interval of 7.5k miles.

What is nice about amsoil is their ordering.Ask a sponser.

I'm not discounting that this could be true or that the oil is great quality, but they only have one type of certified oil currently.

 

[TimVipond]

Amsoil has the 4 XL oils (5W20, 5W30, 10W30, 10W40) and the synthetic blend diesel 15W40 that are API certified.

Buster you had the best used oil analysis ever with Redline but you vote for Amsoil. How much did they pay you?

 

[buster]

sprintman, all oils do well in terms of wear in the 2.4L Honda. Amsoil feels much better in this car than the RL. More power and much quieter. Believe, I'm usually a critic of Amsoil's claims. Amsoil also works better in more engines than Redline and we've seen more than enough proof of that. RL has it's place, but it's just not as good of an oil overall IMO.

 

[sprintman]

#@$%!. Where is your UOA that that shows the Amsoil is better? How much did they pay you? You will not phuck us over. I always knew you were sus when you you knocked back the job in Sydney, a chance to live in G0d's country and you passed it by.

Sprintman - have you any experience with Amsoil? You have a serious problem, my friend. I know you guys ignore your loonies, but there must be one or two shrinks in Aus. Buster has his issues, but he is not suspect, nor is he being paid because his world view does not fit your myopic viewpoint. Get over it and let the man have his opinion.

 

[buster]

sprintman, how many times have I ridiculed Amsoil's 4-ball wear test? Or the price of S2k? Thickening issues? Direct jobber I know that is a liar? That doesn't mean Amsoil is NOT a great oil. It is and I've said over and over that since API SM and over the last 2 years or so, they have stepped up to the plate and become even better.

Their oil filters and oils have proven to be excellent. Terry even acknowledges how much Amsoil has improved. They watch this site. Back when Mobil 1 was still PAO and Amsoil was SL, no I wasn't the biggest fan. You need to realize that oils constantly change. What is good today, might not be tomorrow...get it?

You need to get a clue. Redline specializes in low viscosity racing oils. All those pro teams you see on there website run their racing oils. Their street oils are so so. I've looked at RL and researched it to death only to find it's just not needed in a street car IMO. It's great for shear stability and keeping an engine clean. It works great in some engines. You constantly reference only the used oil analysis of RL that happen to be in engines that ALL oils look good in. So don't lecture me and don't tell me about G0D's country you loon. What does that have to do with anything? My family/friends are here. That is more important not too mention this is a great country as well. Unreal.

I also try and recommend different brands so this board doesn't become "one brand dominant". If 5 people are suggesting Amsoil, I might say why not try PP or something as another option? Nothing wrong with that. *I also play around a lot where some probably take me too serious. Many cases I'm trying to get a laugh out of being sarcastic. That is my humor. Sorry.

Like my joke about Al and the 4-ball wear machine. Bad taste, yes.

Question for you, why are you so defensive when it comes to RL? Do you sell it?

 

[badtlc]

RP 10w30 would get my vote.

 

[Johnny]

Hey guys, lighten up on Sprintman. I don't think he was slamming anyone. Maybe that's his since of humor.

I've said this before and I will say it again, it's just oil. Let's all get along.

Personally I wouldn't bother with any of the boutique oils for normal street use and by the book OCIs. Pennzoil Platinum, Castrol Syntec or Valvoline Synpower would be my choice depending upon availability and price. I avoid Mobil 1 because of it's trend to show higher Fe UOA numbers in certain applications.

If I were limited to the original three choices I would use Redline simply because I can walk into the local parts store and get whatever I would need anytime I need it. Amsoil would be my second choice, even though their marketing turns my stomach. Amsoil seems to consitently make high quality products sold with carnival barker sales tactics. Royal Purple would be last because of the thinning out UOA history posted here, minimal availability and suspect claims to be a horsepower booster.

I like sprintman, and it is just oil.

All I was trying to say is that for what most of us need, I think Amsoil is a better choice. I need an extended drain oil. Redline is superb for racing. It's also more money. Oils change and so will my opinions based on what we see here. Thats all. I can't help the fact that the 0w-20 has made my car noticeably smoother.

For shorter drain intervals, conventional all the way.
