The purp! Planning on switching to Rotella this summer though because I'm tired of hearing the damn lifter tick.

Royal Purple 5w30

pennzoil platinum 5w20

once i win the lottery. royal purple.

Also a Royal Purple 5w-30 fan!! Although a lot of 420a guys run Castrol Synthetic instead.

penz plat 5w-30

Royal Purple 10w30 right now, but when it warms up I will run 10w40.

Penz Plat 5w-30

Penz Plat 5w-30

Castrol Syntec 5w30 pretty much all the time. I might switch to a higher viscosity when summer really kicks in.

ive heard from people that royal purple never lasts and you havea to constantly do oil changes but does it run the same as normal oil cause this summer im working full time so cost shouldnt be a problem but im looking at longevity. and nice todd purple royal FTW.

Whoever said that obviously doesn't know what they're talking about. You should be changing your oil just about every 3k miles anyway.

I change the oil in the Dragon every 1000 or so.

my uncle used to change the oil in his lambo every 750 miles.

honestly, i would be more comfortable using the used oil from his cars than using Quaker State and stuff, haha.

10w-30 mobil 1 synthetic .... and who drives there cars in winter! That is where trucks come into play and who knows what goes into that, I swing by jiffy lube and say take care of it.

5w-30 Mobil 1 in the summer, 0w-20 in the winter.

Our new Ford at work goes 15k between oil changes per the dealer recommendations. I think my car oil gets changed once, maybe 2 times a yeardepending on how hard it's driven.

Castrol Synthetic 5w30

Valvoline Full Synthetic 5w-30 year round... hasn't ever let me down.

ok i wasnt sure i didnt get how it would be different cause im probably gonna run that this summer.

All vehicles the same:

Mobile 1 Syn - 5w-30



And filter...

ditch that royal purple shit !! Test after test it has performed at the bottom of the list. Mobil 1, motul, rotella, redline.....those all perform well and dont cost a fortune...redline is a little more expensive. I run mobil 1 15w 50

yeah im runing mobil 1 right now but i was just weighing my options.

i used to use mobil 1 till they changed up the forumula. if i could get my hands on it i would use european castol ( aka german castrol). for my next engine i will prolly use Vr1 race oil

dont belive everything you read online, sure you googeled it and thats the first thing that popped up. thre are many of the ls series guys that are using it with not failures.

costco has a sale on Mobil 1, beginning 13 may. $9 off normal price per box.

Subaru drivers: you don't need to change the oil so often (5K to 6K is okay), as long as you change the filter every 3K or so.

according to my mechanic its just normal oil with a fancier label.

ill take my chances lol. they said that penzoil platinum was shit until it was tested and found it was only second to german castrol.

That may be true, but I wouldn't waste my time changing the filter to just put old oil back into my engine.

If it's synthetic, any synthetic, at 3K it is not old oil. It's not old oil at even 7K. You don't have to drain the oil. Just replace the filter, and then top up to replace what was in the filter. Saves you $25 to about $45, depending on what oil you are using. That's roughly the cost of a tank of gas in my car.

mobil 1 in the vette 5w-30. walmart supertech full synthetic in my truck and camry 5w-30. Also a big fan of valvoline...have personally seen a chevy 350 ran with conventional 10w-40 valvoline with over 250,000 on it and it finally blew a head gasket...piston tops were clean and could still see swirl marks on the cylinders!!!

I'll stick to changing my oil every 3k. It's not like it's that expensive, and if I'm changing out the filter I might as well change the oil while I'm there.

exactly.

I've always stuck to the rule of every 3k miles no matter what change the oil and filter even if the oil still looks clean and you use a full synthetic there still are contaminants in it that collect over time and it's just best to change it out. I always find a good deal on Valvoline Full Synthetic either at my work or at walmart.

I run Valvoline VR1 20w-50. Only run 20w-50 because I have very loose clearances so I can rev to 9K. Its a race oil so its no the best for DD's. I'm going to go back to Mobil 1 next oil change probably. But after years of Testing oils I'd run Mobil 1 or Torco oils. All oils start off as the same base oils and its the additives that make a difference. When I met with the Torco guys and Bizi at SEMA they showed me a lot of confidential information about what the additives are they use as well as their competitors. Mobil 1 is the only other brand that uses a few special ingredients. I can't remember the names to tell you and I am not supposed to talk about it but I can tell you that Mobil 1 performs great and holds up to heat very good. Not to mention its fairly cheap and almost every store has it so why not run that.

I would run Mobil 1, but I have heard too many horror stories about the oil disappearing in the flat four.

Subaru's love Mobile 1.

every 1500-1700 miles i do tha change up
next!

mobil 1 is so good I feed it to small childeren.

What is really strange is Royal Purple is the only oil my car does not consume like candy. ??? I dont know why, but I live by that shiz.

Run what works for you I say. Most oils are just fine.

Vegetable oil would probably not work so well though.

Royal purple tastes like chicken.

what do you guys think about ams

I've heard great things about AMS, but I've never seen it in a store where I could buy it.

Royal Purple, Redline, and Amsoil are the only true full synthetic oils on the market.

If you want the best information on motor oil go to bobistheoilguy.com and check on those forums.
