![]() ![]() Came home and looked up the Castrol Syntec saftey data sheet. The owner of the store told me it is 100% synthetic (I asked). ![]() That's a myth often promoted at many auto parts stores.Īs to NAPA getting sued? For what? If they sell an oil that meets the specs written on its label - how are they to blame?īy the way - I bought some Castrol Snytec at NAPA recently. All API oil rating are not backwards compatible. By the way, I went 2 miles down the road and got my Gl-1 oil at Tractor Supply. The owner of the store told me there is NO such thing. I recently tried to buy or order some GL-1 trans oil at the NAPA in Alpena Michigan. That and a general lack of knowledge I've found at many NAPA stores. The issue it often what they have in stock in the shelf. ![]() To the converse - a good HD off-road oil with a high level of ZDDP is indeed "substandard" for use in diesel cars and trucks with modern emissions systems.Īnd to be clear - you can order many other oils through NAPA. That also includes many cars and trucks made with flat-tappets. The newest emissions-compliant oils ARE indeed substandard when it comes to use in many older and/or HD machines. Thus most NAPA stores I've been too push the automotive lines of oil - NOT oils well suited for HD off-road stuff. "Substandard" without proper context has no useful meaning. NAPA switched to Deka for many of their HD batteries. That's what NAPA and Sears did recently with the Exide battery company. When they find out they are selling substandard parts - they often change suppliers. I've bought many "substandard" parts at NAPA and other parts resellers. No, not all oil is the same, but if it meets API specs the same as any other oil, they are equivalent.Īs far the NAPA oil, I highly doubt that NAPA would want the resulting lawsuit, and bad publicity from selling a substandard. But the same oil company that bottled the store brand oil, also bottled about 3 other brands of oil that we carried, and countless others that we did not. Same thing, people didn't want the "inferior" oil. We also sold oil in our own bottles with the store brand on them. Of course, they had no problem buying the twice as expensive well known name brand filter right next to it, and guess who manufactured that filter for that company, and about 20-30 others? Never could get some people past the idea that they were inferior. Years ago, I worked at a large auto parts chain, and we sold what people thought was an inferior barnd of oil filter. Aside from that, NAPA does not make oil, they have it made by someone else, who undoubtedly makes it for a lot of other people as well. I think the only way you will get rid of all the moisture is to run the crawler and get the oil warm.Īs far the NAPA oil, I highly doubt that NAPA would want the resulting lawsuit, and bad publicity from selling a substandard. Valvoline Blue and it's got the low anti-wear package and I would not use it in a tractor. My local NAPA is having a 15W-40 diesel oil sale right now. Maybe Deere has a 15W-40"fits-all" oil now with the proper friction modifiers for wet-clutches. Both say nothing about using motor oil in the HL-R trans or steering clutches. In regard to your 455D? I have a 455E and a 450C manual. In 1984 -just about all diesel rated oils had better protection then those do now sold for on-road use. Off-road and racing oils still have the high level of protection, where-as many emissions-certified diesel oils sold at chain stores like NAPA do NOT. In general, oil has not gotten better by "leaps and bounds." Most over-the-counter motor oils have less anti-wear protection - not more then they did 5-40 years ago. Since 1984, oil quality has increased by leeps and bounds. For my 1984 John Deere 455D it reads in my owners manual to use 15W40 in the engine, transmission, hydraulic system and both steering clutches. ![]()
