I have a couple questions. After reading this board I have changed my mind about 5 times as to what oil I want to use. I have a 2005 Nissan Titan with 9000 miles. I want to switch to synthetic oil now. Is anyone familiar with this engine and the seals, and do you think there is any possibility Redline will affect the seals in this engine, 5.6L V-8?

2) My motor calls for 5W 30. I will either use Redline 5W 30, RP 5W 30, or now I am thinking about the GC gold (or green if I can find it) 0W 30. I live in Virginia where we have average (never 0 or below) winters, and 90 degree + (and humid) summers. I pull a boat with this truck. Will the 0 weight GC have any negative affects on my truck? I guess I just dont understand the difference between the 5 and 0?? I did a search here but didnt really get specific answers to these questions.

Thanks for your help. Take it easy on me, I'm still learning.
 
If you want to use Redline and to be 100% sure it doesn't affect your seals, just use a maintenance dose of Auto-Rx(3oz). You can then rest assured that you have the best possible oil(combination) in your engine. I don't think Redline alone will have any negative effect on your seals, but I am not sure. To be sure, it will cost you some 5 bucks, and a risk of having a totally clean engine. Not a bad risk. Considdered the cost of a new engine, this is a small price to pay, if you want your car and engine to perform the best in all situations. However, many here at BITOG would probably disaggree, claiming that the cheapest 0.49cent mineral oil is the best. They can be right, but I doubt it. There is a reason why Formula 1 and Nascar teams do not buy their oil at WalMart.
 
The oils you have listed are all very good oils. Personally, I don't like Castrol, but of course they have shown great UOA's. The first number(0 or 5) is when the oil (and engine) is cold. The second is when the oil is warm. A high number indicates a thicker oil. There are other considderations as well(HTHS a.o.), but this is something you'll find out when you do some investigation.
 
MarkC, You are right. Nissan in Uganda, Tanzania and South Africa do that. However, I do not think a dealer in a industrialised country will do such a thing. Unless he wants you back soon to do 3000 mile OCI or buy a new car. Most people tends to know that the development of synthetic oils was to ensure that an engine gets proper protection over a LONGER period of time, and under SEVERE conditions.

I have an 06 titan with 8500 miles, and switched to synthetics at 5000 miles, so far i have to say that this trucks likes the extra additives.
 
In fact, I think the need for additives in a synthetic is less than in a mineral oil. This is because the base stock is so much better and durable than in a mineral oil. This leads to that it will be a higher percentage of oil(PAO and esters)that will do a better job in your engine than a mineral oil packed with additives. Of course you can make a mineral oil perform as well as a synthetic, but not for as long as the synthetic. When the additivepackage in a mineral oil is used up, the oils performance will drop a lot. In a synthetic, the oil will still perform well, even if the smaller additive package is used up.
 
"If you want to use Redline and to be 100% sure it doesn't affect your seals, just use a maintenance dose of Auto-Rx(3oz)."

I think it is a complete waste of money to put a dose of auto-rx in a new truck with 9K miles. The synthetic oil (if that's what you go with)will quickly remove any varnish (if any) that has accumulated in 9K miles.

I have a 2003 and 2006 Nissan vehicles where "mineral based oils" are recommended in each. The one has 117K on it and still runs like a top with no oil usage using conventional oils. Nissan engines, and the 5.6 liter in particular, are stout pieces.
 
jonny-b,

What sort of mechanism are you proposing? I don't understand what you are suggesting AutoRX will do to prevent seal swell (or shrink) if either were proven to be issues with Redline. Are you suggesting that if an oil swells/softens seals, then AutoRX will shrink them by the exact same amount? But that on the other hand, if an oil shrinks/hardens seals then AutoRX will swell them by exactly the same amount?
 
I don't think Redline will affect your seals, but I am positive it won't do your sea lions any good.
 
If it was my truck,,Schaeffers 5w-40 9000,can get it from site sponsor,or other places,,,would be great in your app.,,use a good filter,as wix,or purolater pure one.........BL
 
Well you could be safe and take the middle road.
Just use a good POA synthetic Amsoil, Mobil 1 Pennzoil Platinum, Schaeffers etc. I am sure I over looked some, but you get the point.

You will then have the best of both worlds! I have been running POAs for about 19yrs and have been very happy with them.
 
I say Penzoil Platinum for $18.50 (5qts) at Wallyworld will get your desired results & save you a few $$ to boot.
 
GMorg, what I say is that Auto-rx cleans better than Redline, so that any contaminations that otherwise would cause oil-leak, won't do so. By the way: Redline put in additives so that seals will not swell/shrink/harden, so that would not be an issue. Did you get it? Auto-Rx cleans better than even Redline does....etc......

Try Pennzoil Platinum from Advance Auto, it's $2.38 a quart after rebate. There's alot of other good oils there on sale to.
 
Id be more worried about that tiny pumpkin on your rear end. than what the oil will do to your engine. the weak link in this truck is its rear end.
