D0ublezer0x Posted January 9, 2014 Posted January 9, 2014 I was wondering what oil you guys can recommend for use in a mildly built big block 402. I know that it was rebuilt 4,500 miles ago and that it has a stock bottom end with an RV cam. I don't know bearing clearances. I plan on eventually putting in a flat tappet hydraulic cam and doing some work to the heads. It won't be driven in the winter and almost never on the track. I know what additives the older motors need but I'm not sure if I want a 40 weight or a 50 weight. Quote
Leghome Posted January 9, 2014 Posted January 9, 2014 I use Mobil One Silver or gold label in my 350ci 290 hrs crate motor. When I change the oil about once a year it comes out almost as golden as it went in. 10W-30 is my chosen weight Quote
72-CLASSIC_RIDE Posted January 9, 2014 Posted January 9, 2014 There are lots of options on the oil used in our cars and you will get different opinions. The higher Zinc content oils are the preferred lubricants. I personally selected Valvoline VH1 Racing Oil in a 10-30 weight for my 402 CI. It has the Zinc content I was looking for and met the criteria I was comfortable with. Been using it exclusively since my rebuild with just over 4000 miles on the fresh motor. Last time I purchased it, was in the $7.00 per quart range. A little pricey but am comfortable it has to date performed as expected. I have also changed it no more than every 2000 miles driven. I will start extending those miles between oil changes out now that I am comfortable the motor has the 4000 plus miles on it. Doug Quote
footballubet Posted January 9, 2014 Posted January 9, 2014 I've run Rotella T 15w-40 since mine was built. Has about 5000 on it now with no problems. Quote
CKZ03 Posted January 9, 2014 Posted January 9, 2014 I use Valvoline VR1 10w30, has high zinc dialkyldithiophosphate concentration (zinc/phosphorous) or ZDDP Here is tons of info on oils, sorry guys I visited another forum http://forums.corvetteforum.com/c3-tech-performance/2484100-list-of-flat-tappet-oils.html Quote
MGD72Monte Posted January 9, 2014 Posted January 9, 2014 I also use Valvoline VR1 10W30, usually order a case through Amazon. With delivery to my door my last case of 12 Qts was $70 so $5.83/Qt. I did some research before choosing this oil and although I still have my doubts about the criticality of using this vice another type of conventional oil for a relatively mild build, the price is not that unreasonable when compared to the cheap stuff I have been using in my daily driver for years (and it also is a flat tappet engine).

Mike 57 Posted January 9, 2014 Posted January 9, 2014 I would try a 10W30 in your choice of brand. I am not sure about the choice of racing oils for extended distance since the detergent package is lower. The Valvoline VR oils in regular and synthetic can be used in street engines. I use Valvoline Specialty Racing Oil ("Not Street Legal") in 10w30. It has a low detergent package. I carry 23 lbs of pressure at 1000 rpm and 77 lbs at 7000. Quote
D0ublezer0x Posted January 9, 2014 Author Posted January 9, 2014 Wow. Lots of guys running VR1. Anyone have experience with Brad Penn? Quote
BowtieThunder Posted January 10, 2014 Posted January 10, 2014 10w-40 or 20w-50 Penzoil in the heat of summer Quote
72MC Posted January 11, 2014 Posted January 11, 2014 If you want the best,....Amsoil,....period. http://oil-tech.com/motoroil-comparison.php I have trusted Amsoil for 15 years and it has been worth every penny. I run the Signature Series 5w-30 in my wife's and my daily drivers and change at 22,000 - 25,000 mile intervals or one year, whichever comes first. And yes, the interval is that high and recommended under normal driving conditions. We put alot of highway miles on our vehicles. As always, just me 2 cents. - Dave Quote
Michael Boyte Posted January 11, 2014 Posted January 11, 2014 We use this in all of our vehicles If you want the best,....Amsoil,....period. http://oil-tech.com/motoroil-comparison.php I have trusted Amsoil for 15 years and it has been worth every penny.

Gonzo Posted January 11, 2014 Posted January 11, 2014 I use Mobil 1 Synthetic in all my trucks and my Monte. With the Monte I also use a zinc additive. My trucks have always have over 200,000 miles at trade in(one of them went to 340,000 when I got rid of it)and the oil always looks good when changing it. 5w30 for all of them. A friend recommended Valvoline Max-Life for higher miles so I'm giving it a try in my daughters cars, so far so good. Good oil pressure, not burning any oil and it looks pretty good at drain time.

Daryl Posted January 31, 2014 Posted January 31, 2014 Of all of you that have chimmed in so far, how many of you are running roller cams? Quote
72MC Posted February 1, 2014 Posted February 1, 2014 I run a full roller assembly in the Monte. - Dave Quote
Sam (Bones) Posted February 1, 2014 Posted February 1, 2014 amsoil here too, in my duramax and my 454 w/ full roller, 350 w/ roller cam I break my engines in with Joe Gibbs break-in oil, then I use the valvoline for the first few thousand miles, then change to amsoil Quote
72jrfan88 Posted February 1, 2014 Posted February 1, 2014 Yes. Love amsoil as well. 10w30 in the 72 350. 5w30 in my 5.3 07 silverado with AFM. 97 monte with 3.1 also gets it and it has 200k miles on it! Quote
dbreese Posted February 1, 2014 Posted February 1, 2014 Joe Gibbs HR 15w-50. Solid roller engine. Amsoil is good stuff also. I use their transmission fluid. David Quote
D0ublezer0x Posted February 2, 2014 Author Posted February 2, 2014 Thanks for the suggestions guys. I'll do a bit more research. Quote
