mobil 1 synethetic oil or royal purple?
 

i normally use motul oil but don't have that option tomorrow and need an oil change asap. I'm running the full blown turbo kit stage 1 premium on e85. which oil is better mobil 1 or royal purple. please help!

Royal purple is garbage haha! Mobil has a number of synthetics, just be sure to go their top tier products if you want to run mobile.

yeah which mobil synthetic is the best. i usually use motul but am at 3200 miles right now and need an oil change asap lol. I'm also still on factory transmission fluid i should prob change that soon too.

I forgot what its called, but the one with the gold cap.

I don't want to be "that guy" but I am not a fan of motul either, but thats a discussion I rather avoid as there are to many brand fan boys out there and it always turns into a sh*tshow.

Mobil 1 ........ now, you can get on with your life ...... :D

Lol yeah we should end this thread now before a oil debate starts

whats your favorite oil when running e85 and a turbo kit

Do lots of research. I personally run Castrol Professional OE 0w-20 exclusively. I do used oil analysis every oil change and have been very very pleased so far.

yeah man are you currently boosted.

I started running Amsoil after seeing this thread:

Can't go wrong with mobil 1 tho

This is what I talk about when you go with special order oils. When you need it, you have to wait till it ships.

If you can live with timing everything to when stuff ships, by all means special order oils is ok.

Big fan of Redline oils myself for the shear resistance. But no question, of your two choices the answer is Mobil 1.

Nope but that oil far exceeds my needs haha. Go do some reading on bob the oil guy forums to find the best oil for your needs. Its better you make your own informed decisions rather then asking some random guy like me on here what oil to run.

and Mobil1 is cheaper too.

Way too late on this response, but changing oil at an arbitrary date/mileage interval is throwing money away.

I throw my money away every 5000km's hahahaha! but your right any premium oil company's (not marketing company that sells oil) top end oil will generally outlast what the filters on our cars can handle. That being said don't try saving money by going with super long intervals, oil changes are cheap preventive maintenance

NAPA also has their own brand of synthetic (which is made by Valvoline) and when on sale, it's usually $3.49 a quart.

Just don't get royal... anything else is good.

Try eneos if you want. O.o you can get them @ napa. It's nice.

"Which oil is better" is not something that anyone here can prove. Both companies offer many different oils and I would be looking at the best oil choice for your particular application when trying to make a decision.

For a boosted car running E85, I would not use the 0W-20 GF-5 oil from Mobil 1 or Royal Purple or any brand. I would be looking at something a little robust and with higher detergency/dispersancy levels. For Mobil1, maybe the 0W-40 since it's a light 40 grade or even the High Mileage line since it has the older API SL levels of anti-wear additives. For Royal Purple, probably the High Performance Street oil in 5W-30.

UOA's here have shown that with a very good tune you can run GF-5 0W-20 oils with good results, but there isn't anything wrong with maybe stepping up the viscosity and/or or the anti-wear/detergent package. And I definitely wouldn't make a decision based on how someone feels about brand x over brand y. Sure, RP offers low bang for the buck, but that doesn't mean it sucks and they do have a nice variety of oils to choose from (GF-5, high performance street, and pure racing).

All I can really add is do UOA until you find an oil your happy with, that is the only way to get the right oil you want.
