TL;DR Purpose-built for pre-2006 GM and pre-2008 Ford automatics · Mobil 1 fully covers Dexron III, Mercon V, Allison C-4, and JASO 1-A. This is a legacy-spec fluid by design; it is the correct choice for the transmissions it targets. Not for vehicles requiring Dexron VI, Mercon LV, Toyota WS, or ZF Lifeguard. No shudder resolution data found.
This PAO-containing synthetic blend is built specifically for older GM and Ford automatics · the ones that shipped with Dexron III or Mercon V in the owner's manual. It covers that spec family completely: Dexron III/IIIG/IIIH/IIE/IID/II, Mercon/Mercon V, Allison C-4, and JASO 1-A, all verified on the manufacturer's product page. The PAO component (20-<30% per SDS §3) puts it in genuine synthetic territory, which means better low-temperature flow and oxidation resistance than a mineral-oil ATF of the same spec. The product is not approved for Dexron VI, Mercon LV, Toyota WS, or ZF Lifeguard. That's not a gap · those are different specifications for different transmissions. This fluid was never designed for them.
Right choice for owners of pre-2006 GM automatics (Dexron III), pre-2008 Ford automatics (Mercon/Mercon V), and applications requiring Allison C-4 or JASO 1-A. Always confirm the spec in your vehicle's owner manual before purchasing. Skip if your vehicle requires Dexron VI (2006+ GM), Mercon LV (2008+ Ford), Toyota WS, or any ZF Lifeguard specification. Using the wrong ATF spec causes transmission damage.
The SDS classifies this product as not hazardous · no signal word, no GHS codes at mixture level. Dispose of spent ATF at a used-oil collection facility; do not pour down storm drains or into soil.
No. This product is designed for older GM automatics requiring Dexron III · the standard spec through the early-to-mid 2000s. Dexron VI is a different, more recent spec required by GM for most 6-speed and newer automatics from 2006 onward. Use a fluid with confirmed Dexron VI approval for 2006+ GM vehicles.
No. This product holds Mercon V approval, not Mercon LV. Mercon LV is Ford's low-viscosity spec introduced for 2008+ 6-speed automatics. Mercon LV and Mercon V are not interchangeable. Use a Mercon LV-approved fluid for 2008+ Ford vehicles.
It is the right fluid for pre-2006 GM automatics requiring Dexron III, pre-2008 Ford automatics requiring Mercon or Mercon V, and applications calling for Allison C-4 or JASO 1-A. Always verify your vehicle's owner manual spec requirement before purchasing.
It contains a PAO (polyalphaolefin) component (1-Decene homopolymer hydrogenated, 20-<30% per SDS §3), which qualifies the 'synthetic' label. The dominant base stock by volume is severely hydrotreated heavy paraffinic distillate (50-<60%), making this a PAO-containing synthetic blend rather than a pure PAO or ester-base ATF.
