Just put a ZZ4 in my 85 Z and was wondering what your opinions are on oils and weights?

 

Hey 85ZZ4TPI I use reg. Mobil 5w30. When i get 4000 miles on my new motor i will change to Mobil 1 Synthetic.

Larry-Im runnin 10-30 mobil1. How did you route your bypass hose for the throttle body?

 

85ZZ4TPI check out F-Body.Org. I got the instructions from there. I believe i'ts under FAQ.

I run 10w30 in mine. Oh yeah and in case you missed the recent posts, don't use a Fram oil filter. Using the AC Delco filter is the common recommendion, I'm running the Bosch w/ good luck.

AMSOIL 10W30 synthetic in the Camaro, 0W30 synthetic in the 396. AMSOIL filters on both (best filter out there).

Show that new powerplant some respect and use the best. Anyone who uses petroleum based oil in a healthy engine has no respect for their machinery. Using a "me-too" synthetic isn't much better (Valvoline, Penzoil, Castrol, etc.).

Mobil One 10w30. 120k miles, never apart (so I've been told). Needs valve seals. Amsoil, Redline, and Royal Purple (Maxoil) are the best, but expensive. Too high for my old beater (until the stroker comes, anyway).

------------------
New (to me) 87 Formula 350. Edelbrock TES, Flowmaster, airfoil, K&N in modified airbox, March underdrive pullies, still slow....for now.

 

this might sound a bit heavy, but my oil pump aint quite the best.. so in the summer i run 15w40, and 10w30 in the winter.. i always use a wix or delco filter..

 

Mobil 1 10W30, naturally.

Castrol GTX 5W30 or 10W30 depending on the season.

 

all kinds I have an oil leak (really crappy mechanic did the work<img src=http://smilecwm.tripod.com/cwm/angryfire.gif>) but I would normaly run 20w50 castrol sintech

 

85ZZ4TPI, use whatever grade oil your engine specifies, synthetic is best, but damn expensive.

I run 5W30 in the RS, 10W40 in the 79, due to it's 60 over boring. Valvoline all the way..

Mobil 1 15W-50 PF-35 Filter

 

Remember, oil film thickness between the ring face & the cylinder bore is influenced by oil viscosity. The lower the viscosity, the less oil film thickness which translates to higher ring face & bore wear over time. I would recommend 10W30 as absoulte minimum, with 10W40 being prefered for hot weather driving, especially if engine is pushed "hard".

I run Mobile 1 synthetic 15W-40 in the 3 hot summer months, and 10W-40 the rest of the time. I do use Amsoil from time to time when money...and the wife allows!

Mobil One 5w30 with an AC filter. What weight is recomended? I have been wondering if this is too thin for an L98? It holds good oil pressure.

87 Formula 350 14.81@91.64

What is the matter with FRAM? My dad and I have used them in all our cars with out flaw.

 

Mobil 1 15W-50 with AC or Wix Filter

 

Valvoline 10W40 (I like how clear it is) and AC PF35 oil filter. When I put the new engine in, I will be running Mobil 1 synthetic, but not sure about the weight.

15W-40 Delo 400. It's in everything I own. What's more important is how often you change the oil and filter. I try to get it out before 3500 miles and always before 4000.

 

i use pennzoil 5-30, pennzoil 10-30, mobil1 10-30. mobil 1 15-50, seems i run a differant oil in each engine. all ac or wix filters.

Use a good quality oil and filter and CHANGE it EVERY 3000 miles. The best oil in the world won't protect your engine if the oil is worn out or dirty.

15W50 Mobil 1 and AC PF25 on the 'F' car. I only use the car in the summer. The daily drivers get 10W30 Mobil 1 and the appropriate AC oil filter every 3,000 miles in colder weather (down to -35°F) and 15W50 in the summer.

I wouldn't use anything with much lower viscosity than 10W (ISO 46), especially in a synthetic. The pour point is more than low enough for anything I'll ever encouter, and teh high temperature protection is much better than mineral oils.

I had 10W30 Mobil 1 in the case last year when the temp hit -37°F with my wife's Astro parked outside the cabin, in the wind. The battery was definitely a little "less fresh" in the morning when I started it, but it cranked and fired with no problems and no detectable noise from lack of lubrication. I think I would have been a screwed puppy with 5W30 mineral oil, for sure. Besides, I like my engines too much to use 5W-anything at highway speeds and loads. One set of bearings for every 300,000 miles is plenty for me.

Castrol 10w30 in the f-body, and my dad's 2000 Galant.. Castrol 5w20(isn't that ****ing scary!) in the Civic.. even worse.. Ford uses 5w20 in freakin 5.4L triton V8's.. in Expeditions and whatnot.. want to void your warranty.. go ahead and use something else.. That just scares me.

when the time comes to put a new motor in the RS I'll break her in with either Castrol or Valvoline.. and it's Mobil 1 or Royal Purple from then on.

Check out this technical article for information on filters. You may think twice about ever using a FRAM again.

I personally use Valvoline 20W-50, with AC filters for the IROC. Valvoline 10W-40 for the pickup.

 

what is the best oil filter to use.by ac do you mean ac delco
