datzenmike Posted April 20, 2011 Report Share Posted April 20, 2011 Going into warmer weather it depends on how hot you expect it to get before the next oil change.10W30 will likely do maybe 20W40 or even 20W50. All oils have to meet minimum standards so any will do but you can't go wrong with a name brand. Lately oils have seen a reduction in in anti scuff additives like ZDDP. This is because today's cars use roller rockers and catalytic converters that are damaged by this additive. To protect our older cams and rockers try to find oils with this additive. Some special oils still have it in them or you can buy it and add to your oil. Diesel oil is still high in ZDDP but diesel oil is highly detergent and may clean your motor too well and remove carbon from around the rings that is actually helping preserve compression.

thisismatt Posted April 20, 2011 Report Share Posted April 20, 2011 Castrol GTX, Valvoline, or Mobile 1. Typically Castrol GTX, unless Valvoline is cheaper, or Mobile 1 is on sale. 5/10w30, or 5/10w40. Quote Link to comment
Laecaon Posted April 20, 2011 Report Share Posted April 20, 2011 Castrol GTX only. I like Castrol oils. 10w30 usually. Quote Link to comment

HRH Posted April 20, 2011 Report Share Posted April 20, 2011 How much is your motor worth? I run Royal Purple in all my rigs except the D21, because I'm waiting 3000 miles before I switch to synthetic. They mention that on the bottle, think they recommend 2000 miles before switching for new motors. Right now I'm using NAPA brand oil, which is basically Valvoline base stock minus their additive package. I also run the Royal Purple 6000 miles and change the filter at 3000, except the 510. It gets changed sooner than 3000 usually because it's the race car and I care a lot more about it. The other good thing about Royal Purple is it's an SL oil, not an SM. So all the zinc stuff and other additives that people are missing, have never been taken out of their oil. They didn't change their formula because they called bullshit on the American Petroleum Institute. Same with Red Line, they make oils that are suitable for GL-4, though I don't know if they're an SL or SM oil. If you didn't know, most Datsuns need GL4 ONLY in their transmissions due to brass synchros. (The yellow metal problem.) Cummins diesel NV4500 transmissions also require a GL4 fluid. That's one reason I haven't used Schaeffer's yet. It's good oil, but they only have a GL5 gear lube. Other good oils: Schaeffers, Red Line, Valvoline. Regardless, if it's just a driver, nothing special, stick with a tier III base oil (Castrol/Valvoline/Mobil1) and you can't go wrong. Stick away from Pennzoil and Quaker State. Also, if you have a leaky engine, don't use synthetic oil. It cleans really well, and will clean all the gunk keeping your old, cracked seal from leaking badly, and then you'll have much more leakage. For non oil-leaking motors and new motors, no reason not to use synthetic. (Other than cost.) Oh yeah, and FRAM filters suck. You might as well take a tampon, wrap it in a plastic bag, and duct tape that to your oil filter housing. It'll do the same thing. :D 1 Quote Link to comment

SHAMUS'WAGON Posted April 20, 2011 Report Share Posted April 20, 2011 For the last two years I've been dripping out the empties from the trash outside my work. I get about a half a gallon every other week. So it really doesn't matter what you dump in there. The only thing I suggest is stay away from synthetics. Especially if you have gasket sealant on your rig. Synthetic motor oils chemically attack gasket sealants, and you'll end up with leaks all over. That's why they are not recommended for high mileage motors. Quote Link to comment
BRE_dAtSuN Posted April 20, 2011 Report Share Posted April 20, 2011 i use 20w50 valvoline vr1 has zppd its non synthetic so its not expensive and its perfect for a street/track motor Quote Link to comment
1968F-100 Posted November 16, 2023 Report Share Posted November 16, 2023 I realize this thread is a decade plus old, but I thought I would share a bit of info with the board. The Haynes manual clearly states Castrol GTX motor oil and HYPOY for the manual trans. (GL4). Castrol informed me they no longer make any GL4 product, and have widen the GTX branding to include a GTX Classic. If you want the product with higher zinc content, you should find the GTX Classic. just throwing it out there. 1 Quote Link to comment
