I have been using Royal Purple for the last 4 oil changes. Roughly 5k per change. They say it can run up higher then 5k but i notice that it will get sluggish if you push more than 5K. I did notice an increase in millage just as Yanki01 did but I think that I am getting between 285 to almost 300. Usually average 29 miles per gallon.

HP for sure went up as well as the engine runs smoother as well. Easier starts in the cold as well.

For filter I use Mobil 1. From what I have heard the K&N filters are not worth it because they will clog before or around 3k miles of use.

 

I was kidding. I would rather use cow urine than Pennzoil.

 

do you guys check your old oil when you do change oil? if not, then i suggest you guys do it.. many use mileage as basis for the next change oil, but one thing you should consider is that cars experience different driving conditions like driving habits, loads, city or highway driving and such.. Even though you are on time with 5k oil change when you see that your oil is so dirty then you might wanna change it earlier next time, and just because you got full synthetic doesnt mean you will change you oil for extended miles, thats ok if your oil is still clean and your driving condition is not that heavy that requires you a more frequent change.. Synthetic oils are only more stable oils that burns less but doesnt mean you change oil every 8k miles coz they say its fine.. 5k miles oil change should only be an estimate (ballpark) you should adjust it depends on use

 

Hmm What should i use for my first oil change in 2 months? Im deciding between Mobil1 and Royal Purple. For my last tc i just went to jiffy lube but idk what kind of oil they use.

 

Jiffy Lube uses Pennzoil, aka tar.

 

Oh crap! Well thats good to know Thanks!.

 

Thats what i figured Carbon but one of those really good oil websites the one i found threw one of the threads about oil on here says that the Pennzoil Full Synthetic is actually better than Mobil1. But I think I should be fine with my Royal Purple. Although I need to have my engine looked at by Toyota for my rough idle.

 

well i use royal purple n yea i can fell da difference in da engine it runs more smoth n my mpg is been a lil better since i started using it n it doesnt burn as quick like da other ones i had

 

Ive been using Royal Purple 5w20 for the last 50k miles or so on my 07 tc - yes I drive *alot* - and I am averaging roughly 27-28 miles per gallon consistently. thats with the sunroof open all the time.

 

yet again MOBIL 1

 

Used Mobil 1 Full Synthetic after my first oil change and it ran about as good as it did with the regular oil. After switching to Royal Purple I noticed a nice difference in how smooth the car ran. The main difference was after shifting. It felt like the motor was experiencing less stress under all conditions. I will forever use Royal Purple!

 

bump bump ;)

I think Royal Purple might be the oil to buy ;)

like I stated before I did notice a small HP & MPG gain in the Honda CR-V ;) I can only hope & prey that I will see the same gains in the tC

bump bump

 

hm i know people that use/used royal purple they liked it i personally never tried it. i use to run castrol syntec on all my cars and then i went to mobil1 never goin bak to any other type of oil i guess i gotta give the royal a shot

 

royal purple ftw

 

Actually, let me rephrase that. Jiffy Lube pushes to sell Pennzoil because it's their highest profiting oil. You can request a better oil or bring your own oil. However, with the way Jiffy Lube does things, I wouldn't doubt that they'd keep your good oil and put the Pennzoil in your car. Actually, they would probably not do the oil change all together.

 

In regards to the brands I am sure all have pros and cons. To break it down simply switch to a synthetic if you are not already running one, they help to clean out the goop, and leave a nice film promoting less friction and more mpg. If you are NA stretch the oil change out till 7000 miles or so but change the filter at around 3500 as they start to loose the ability to do thier job around 4000 miles or so and this is all filters not just K&N, FRAM or OEM. Don't forget to top off after a filter change! If you are boosted go with a standard oil change interval. I notice a smoother running motor and 2mpg increase about 6000 miles into my switch over, btw I only ran the first oil change to 4000 and dumped it to get what ever oil was left from before the swap and contaminants out.

 

i was also wondering which oil to use...and now i am leanning towards Royal Purple since so many people find its good to use!!

 

warren, let me know if u want amsoil, i get all there stuff at wholesale, even the ngk plugs, wipers, and mothers stuff, basically anything on there site.

ive been running amsoil in all my cars and gf car and all family cars for about 3 years and its awesome stuff, u can feel the difference, especially tranny fluid, man that ____ is awesome, we did curtis's xb bout 3 months ago too and he loves it...

 

Um how do you change your oil filter without losing oil. You pull that bad boy off and all that wonderful oil spills. Is there a secret I dotn know about.

 

I dont think you will lose a lot of oil, most of the oil are in the oil pan, may a lil spill and the oil on the filter is all that you will lose
