I searched and nothing came up.
I’m not sure what weight to use, but I called three different machine shops and 2 said use Valvoline 20w50 and one said another said Castrol 20w50. They all said to use the comp cams oil additive with zddp. Is that too thin of oil? I give up. I’ve got 5 quarts of NAPA 20w50 (Valvoline) ready to go in with the comp cams oil additive. What are you running? You call any performance shops they want to sell you Joe Gibbs oil $$$. s/t

Re: Engine builder says to use valvoline 20w50
They're recommending the VR-1 20w-50 because it still has plenty of zddp in it already, without the additional additive. I flattened a (new) cam a while back from not using the propper oil. Just use the Valvoline VR-1 and you should be fine. I use it in my truck.

Re: Engine builder says to use valvoline 20w50
They didn't specify the VR-1 they said "any good oil, like Valvoline".
The VR-1 I'm sure is a fine oil though. s/t

Re: Engine builder says to use valvoline 20w50
If you can't find VR-1 try the DELO 400 oil, it has a good amount of ZZDP in it, and of course along with the Crane super lube or the tried and true EOS from GM, I bought mine at the local dealer for $18
never lost a cam with this combo.

Re: Engine builder says to use valvoline 20w50
The best oil for camshaft's is Brad Penn oil. It has high zinc levels and can be ran with any mechanical, roller, or hydraulic cams.

Re: Engine builder says to use valvoline 20w50
Just curious... Why 20W50? Recent rebuild? Racing engine?

Re: Engine builder says to use valvoline 20w50
You can use any oil you want - BUT - use an additive - GM EOS (1/2 bottle per oil change - full bottle for breakin)
Comp, Jegs, Summit all make additives as well I use Lubriplate GPO motor oil myself - they still have plenty zinc - cheaper than Joe Gibbs - and they pay the freight to my door when I buy it by case Please also use a NAPA gold filter - NAPA, wix make the best filters

Re: Engine builder says to use valvoline 20w50
What about Royal Purple? They've got a break in oil that says it's for flat lifter cams.

Re: Engine builder says to use valvoline 20w50
I used to use 10W30. Then on a really HOT summer day a mechanic told me I should be using heavier oil. I live in a moderate climate, Vancouver Is., where temps rarely go below freezing for any length of time. I think by using 20W50 exclusively since 1995 I have prolonged the life of my engine. Old engines run smoother with heavier viscosities between all those worn moving parts.

Re: Engine builder says to use valvoline 20w50
The formulation of EOS did not change - they had to change the part number and description so it would not be used with catalytic converter cars.
I found a bunch (10 bottles) under the old part number at the local pontiac dealer - they where thrilled to sell me all 10 bottles for 4.99 per bottle to get the old part number out of inventory

Re: Engine builder says to use valvoline 20w50
Use a whole bottle during breakin - after that use 1/2 a bottle per oil change

Re: Engine builder says to use valvoline 20w50
FYI - a couple of folks posted synthetic oils - breaking in with synthetic oil is normally a no no ---- they are to slick and will not allow your lifters to spin in the bores and on your cam lobe - this will cause premature wear and wipe your cam

Re: Engine builder says to use valvoline 20w50
Ive done just what my engine builder taught me 15 years ago and never had a problem. About 5 years ago he added the part about the break in oil.
Build the engine with 70 wt oil on all the bearing surfaces and the best cam lube you can find on the lobes. I use some stuff that he gets from a custom grinder he uses. I cant remember the name. Been awhile since I put a bottom end together. The one im doing currently he built the bottom end for. Anyway I use straight 30 weight oil and a bottle of break in oil for 5 hours. Change the oil to 10/30 valvoline and another bottle of break in oil till the first oil change. After that I switch to castrol syntec and i have never had a lobe flatten. Now there are lots of recipies for break-in and every engine builder will give you a different one almost guaranteed. Most older ones like valvoline cause its one of the top proven brands thats been around as long as oil has been. Usually the best thing to do is pick the one that works for you and stick with it.

Re: Engine builder says to use valvoline 20w50
I have gotten to where I use 20w 50 in anything but my two new drivers, this includes my trucks and tractors. I use the manufacturers recommended weight royal purple in my two drivers (08 mustang and 08 charger).

Re: Engine builder says to use valvoline 20w50
Don't go the Delo route that is for Diesel only. The ZZDP is rated at differnt levels. They are actually starting to take that out of Delo also. Actually went to an intersting seminar from Gibbs oil. Because of the heat of a diesel it reacts much different then say you street car. Any oil that says that its for off road use only has the additive in it. Why not just buy your regular oil and add the comp additive. Dont run a synthetic till the motor is broken in, maybe 2000 miles. Got to get everything to seat and the thing that needs to seat the most is rings.
