This oil works pretty **** good.

Seen Horsepower Tv one morning and they tested out an engine that used regular motor oil, dyno'd it and came out with a baseline hp/tq. After they switched oils and ran the engine on the dyno the car gained 8 hp and 8 lbtq.

I doubt you will notice a difference with your car, but atlesst you know you gained something more out of a regular oil change. A quart cost me about $8.... but when you have the money its no problem... I suggest this to all my fellow dsm'rs

i use this all the time, but recently switched to Mobil1

The best one in my opinion but its the most expensive.

yep i used this oil on my charger works great just dont cheap out on the filters.

I have heard a lot about Royal Purple.

Is it really that amazing?

give it a try find out for yourself.

Fram tough guard is what i purchased for the oil filter... Didn't know of any good others

My car burns a quart every 2-3 weeks so thid wouldn't be very economical for me...

I cannot see how using different oil gives 8 HP. Can someone explain how that works? I have always used Valvoline Synthetic.

There is relatively little factual information regarding royal purple as far as VOA's and UOA's are concerned. For one, Royal purple tends to have higher levels of lead in it as a friction reducer. Bad for cats, doesnt always meet the latest oil requirements, however I am not sure which they are up to at the moment.

Also, royal purple will have a lower viscosity. Now the viscosity and weight of the oil are independent of each other. For example, motor oil can be rated as Xw30, assuming under the 30w conditions, the viscosity is between 9.3 and 12.5 cst (centistokes). In the lubrication world, this is a big difference. Royal purple's synthetic viscosity at 100*c (a typical standard of operating temperature, along with 40*c) is thinner than several other oils, which is what allows less drag.

Comparing 10w30, Mobil1, Amsoil 7500, Castrol syntec, Pennzoil Platinum, Pennzoil CONVENTIONAL, Valvoline MAX Life, and Conventional Castrol GTX are all equal or less viscous than Royal Purple.

A lot of it is marketing, Amsoil 7500 is regarded as an excellent oil. There are racing oils which outperform these oils however can damage cats and typically are not recommended for street driving due to a lack of additives.

i only use the mobil filters on all my cars nothing more cant tell the difference from mobil to the k&n.

I use K&n

+1 don't trust any other.

I also use mobile filters.

Fram is the worst possible, they use cardboard to filter the oil.

The dyno gains are easy to alter the simple use of a fan to blow on to the radiator or intercooler can net power gains.

Fram is junk!

Fram tough-guard filters have a great filtration rating, up there with Mobil1, however they have one major flaw which explains why my car, after 117k miles @ 3k intervals has not seen ONE fram oil filter.... Paper end caps on the filtration media. Most filters either use steel or a silicon type material that "caps" the pleated filter. Fram uses cardboard, that, over time, can become soft and saturated and has been known to deteriorate and appear in the drained oil after an oil change.

K&N is very similar to Mobil1, Both being made by champion laboratories. Purolator Pure1 is another outstanding filter, with excellent filtration ratings.

ehh god damnit lol. Should I change it again? I mean... its brand new so I shouldnt have to worry about anything right??? my motor almost has 130k on it

No, I would not worry about it. Just change it either at 3 months or 3k, whichever comes first. In the case of the filter, the time does matter because the oil is saturating it. Its a shame, because 3k intervals are short for synthetic.

As far as synthetics, Royal Purple is a decent oil it is just very expensive. Mobil1, Pennzoil Platinum and Amsoil 7500 are all very good synthetic oils. Castrol is another good one. Pretty much all name brand oils are good, and surprisingly, Walmart Supertech is very similar to Motorcraft oil and has shown to perform well in UOA's.

Personally, I do not use synthetic oil in my car and I have 117k on a 2001. I use quaker state mostly because I can usually get it for less than 2$/qt. I am a firm believe in frequency of oil changes on conventional oil compared to long OCI's on synthetic. Many people even go 5k on conventional oil and UOA's have shown the oil has performed well after this interval, but I stick to three because I take many short (10 minute) drives.

Jim

well If i change the filter, I dont have to change the oil again right? im not spending another $50 on oil

This is a very interesting topic and as much info you can provide us it's very helpful I was wondering on which brands of oil and oil filters. I will check if on the local retailers we have those brands
