The M1 TurboDiesel Truck 5W/40 is the same thing as their Delvac1, but for about $10/gallon less. It is the only M1 that is still fully Group IV and it's bulletproof stuff for any engine (gas or diesel). I have been using it up to 15K miles between changes and the engine is perfect after 80000 miles. Any oil that can tolerate 20:1 compression with 20-30PSI of boost, with the heavy soot load of fuel oil is going to kick *** in a gas motor. No worries.

yea dude, i love eneos... im running now on 6k miles... im starting to notice the ware on the oil now but still revs very smooth

 

Cool I'm going to order some today. Which one did you end up running

 

i just read all the pages in the thread, and its safe to say that i will be switching to GC on my next oil change but i still have one question though. i live in NY and it can get really cold in the winters and really hot during the summers. is this 0w-30 ok for my engine?

GREAT THREAD!

 

i just run the normal 5w30... they carry a 0w30 but i dont see the point... it doesnt really matter anyways cali has good weather... but my entire oil change including a K&N micro oil filter and autobacs labor runs me $65 which isnt bad for the kind of oil im getting

 

What filter does everyone use? I'm heading to the dealer today to get a new crush washer, and I didn't know if I should pick up a filter or just use one from Autozone. I remember reading something about using a larger filter, but I can't remember the part number. I'm probably going to end up using Amsoil 5w30 synthetic for the next oil change. I'll probably still change it around 4-5k miles, because we do a lot of short trips and stop and go type driving. We've had the car almost a year and it's just now approaching 7500 miles.

 

Thanks for the info Derek. I switched to Castrol today since I was due for a change.

 

I still use the oem filters. If it's good enough for UMS Tuning and Forged Performance, it is good enough for me.

 

0W30 is good for cold weather like that.

 

Okay....which AMSOIL should I buy for the G? the website has so many different options on the online store......

 

Anyone have any experience with the reusable filter sold by PurePower? I was in their website (gopurepower.com) and they make a stainless steel mesh filter, allegedly superior to any of the fiber throw away filters on the market. It sells for $200 plus they sell different types of oils. One of he guys @ work uses the filter and one of their oils in his Harley-D. and tells me he can really tell the difference.

 

According to Eneos, their 0w-20 is group 3/4 blend, and their 0w-50 is group 4 (PAO). SInce the correspondence was from Eneos USA; Im assuming their euro/jdm products might be composed differently. Was yours for sale in America? Or imported....

 

I've read all the threads but please explain if it's ok to use the 0W/30 in Florida's heat or should I be looking for 5W/30?

 

just got some 2000 series amsoil 0w-30 for my 2003 6mt coupe and a new amsoil filter....

whoooooo weee, after 5,000 miles on mobil-1, this stuff is tha shiznit. this is no joke but RIGHT when i turned on the car after 5 quarts of amsoil, i could feel such a HUGE difference. the engine seemed smoother. maybe cuz it was all that sludge inside my engine. the pitch black nastiness was flowing out of my drain plug. it was so nasty. and globs of weird stuff was flowing out too....ugh =/

amsoil = dope !!

 

I changed my oil with Mobile 1 the later part of 06. I don't do more than 6,000 miles a year. Do you think I have the original synthetic Mobile 1 formula in that change? Also, is it of ok to use 0W/30 in Florida's heat or should I be looking at another grade?
