thisismatt Posted September 30, 2012 Report Share Posted September 30, 2012 Mike, do you know if Mobil Delvac 1300 15w40 is good? Quote Link to comment
BJW's FiveTen's Posted September 30, 2012 Report Share Posted September 30, 2012 Delo 15-40 in all my Gas and Diesel cars for 15+ years. The Diesel oil like Delo has way more zinc in it. Never had any oiling issues. All my cars are run very hard. I do change oil regularly and use good oem filters Quote Link to comment
Jdm720 Posted September 30, 2012 Report Share Posted September 30, 2012 Last oil change I did I used Redline 10w 30 with a Baldwin... That was at 269k... I'm now almost at 278k..... Shit still looks/smells good :thumbup: But I did buy some Mobil 1 synthetic of the same viscosity yesterday, K&N filter... Oil change scheduled for tomorrow morning Quote Link to comment
SHORTDOG Posted September 30, 2012 Report Share Posted September 30, 2012 Changing it after only 9 miles?? :confused: Quote Link to comment
Jdm720 Posted September 30, 2012 Report Share Posted September 30, 2012 Yea, I really push my truck... Really.... I'm surprised I haven't really had any major issues for daily driving it for almost a year already Quote Link to comment
SHORTDOG Posted September 30, 2012 Report Share Posted September 30, 2012 But 9 miles?? I mean how hard could you really push it that you would have to change the oil after only 9 miles? I don't know where you work but that would seem to me like going to work and back.. Quote Link to comment
Jdm720 Posted September 30, 2012 Report Share Posted September 30, 2012 9k... Nine thousand :blush: Quote Link to comment

Edward Stills Posted January 7, 2022 Report Share Posted January 7, 2022 Hey guys. New to the forum and excited to be here. I just recently purchased a nice 1984 720 with 92k and a rebuilt motor. The cool thing is that I'm the second owner. Anyhow, the motor only had 150 miles on it when I purchased so I'm approaching this subject of oil with much caution. The last post here was 2013 and a lot of things have changed and one of those things is oil. The only oil I can find on the shelf with ZDDP is Valvoline VR1 20w50. I cannot find the suggest oils (Rotella T 15w40 or Delo 400 w/zinc) on the shelves. So my next option would be using the mfg recommended oil weight (5w30, 10w40 or 10w30 depending on temps) with a ZDDP additive. Any guidance or opinions would be great! Quote Link to comment
thisismatt Posted January 7, 2022 Report Share Posted January 7, 2022 I've found it difficult to get accurate/concrete facts about the amount of ZDDP in oils. ZDDP was removed because it ruins catalytic converters and can cause cat failures before OEM emissions warranties (100k?) expired. I would look for an explicit claim of ZDDP levels, or use an additive. I don't trust that some of the previous oils that used to have sufficient ZDDP still do. Quote Link to comment
Draker Posted January 7, 2022 Report Share Posted January 7, 2022 Delo diesel oil has been recommended many times. Seems to work good, cheap. High levels of zddp. Or just use an additive. Quote Link to comment
Hawaiian620 Posted January 14, 2022 Report Share Posted January 14, 2022 I'm up for an oil change and when getting oil was advised not to run Delo 400 SAE 15w40. I trust the ratsun dudes more than the Orilleys manager who claims to have owned many of datsuns. Should I just run the 5w30 and find the additives instead of the delo 400? Quote Link to comment
banzai510(hainz) Posted January 14, 2022 Report Share Posted January 14, 2022 5-30 too thin unless you live in Iceland Delo should be fine Quote Link to comment

Too early for that. I gotta run to another place for a filter anyways. Thanks for the quick response! Quote Link to comment
datzenmike Posted January 14, 2022 Report Share Posted January 14, 2022 Never use anything with a 5 weight. The 'weight' is based on the lowest average temperature you expect before the next oil change. 10w30 is good to just below freezing. A few days at -5 won't harm anything.

There must be diesel trucks in SC, impossible that there are not. They all need oil so ask them where Shell Rotella T4 is sold or try a Shell service station. Chevron Delo 400 is same, try Chevron station, Esso also makes one can't remember name. Any after market 'racing oil' such as made by Valvoline and others will also do. Go to the counterman and ask for an oil with high ZDDP for your 'flat tappet' chev/ford/dodge circle track car. He'll now what you need and want. Quote Link to comment
Madkaw Posted January 16, 2022 Report Share Posted January 16, 2022 Rotella 15w40 in my stroker Z and in my Z24. Not even synthetic - just the cheap stuff . Quote Link to comment
datzenmike Posted January 16, 2022 Report Share Posted January 16, 2022 It's available in 10w30 as well. Quote Link to comment
