half dozen.9L/7.3L IDI Engine Oil Recommendations

Diesel Hub recommends the post-obit products for vehicles equipped with the 6.9L or 7.3L IDI:

Amsoil synthetic engine oils offer:

• Superior protection confronting fuel dilution and oil consumption

• Superior resilience against thermal, mechanical, and chemical breakdown of engine oil

• Improved oil period and engine protection in sub-zero temperatures and during cold starts

Amsoil is a leading manufacturer of synthetic oils and lubricants, including a line of motor oils engineered to see the demands specific to diesel engines, old, crumbling, or new.

Draining the engine oil

• The drain plug is located at the bottom of the engine'southward oil pan (ruby-red arrow in image).

Locating engine oil fill

• The oil fill on the 6.9/7.3 IDI is located near the front end, center of the engine (scarlet arrow in image) at the top of the injection pump gear cover. If the cap's rubber seal is worn, rotted, and/or deteriorating, replace it; it is an inexpensive item and you lot do not want chunks of rubber dropping into the front cover.

Engine oil draining

• Place a bleed pan below the engine oil pan and remove the bleed plug, which should require a iii/4" wrench. In one case the oil has drained completely, make clean and supersede the plug. Re-installation of the plug should be done by manus first to ensure cantankerous threading does not occur. Snug with a wrench, but do not overtighten.

Engine oil filter removal

• The oil filter is located on the driver's side of the engine, virtually the cease of the oil cooler and to the side of the oil pan. Place your oil drain pan nether the filter and remove information technology. If the previous filter was not over tightened, you should be able to costless it without a filter wrench. If you lot tin't loosen it, you'll need an oil filter wrench or large set of channel locks (fortunately, there is plenty of workspace).

• Double check that the quondam oil filter gasket did not stick to the oil filter mount. Make clean the mounting surface with a clean rag.

Engine oil and filter selection

• You volition need 10 quarts of fresh engine oil and a new engine oil filter. Nosotros are using Amsoil full synthetic 15W-40 diesel oil. If you lot have not converted to a full synthetic, the level of protection greatly exceeds that of conventional "dino" engine oils, and the oil is less susceptible to thermal breakdown and shear. A conventional (petroleum based) oil is perfectly adequate for the IDI, but we believe synthetic oil is well worth the additional cost.

Amsoil motor oil and Motorcraft oil filter

• Stay away from inexpensive or generic brand oil filters. We only recommend Motorcraft brand oil filters. The Ford part number is FL-784; a larger FL-1995 designed for the 1st generation 7.3L Ability Stroke volition also fit, but yous will demand to add 1 quart of oil to the total chapters (full becomes 11 quarts).

Installing Motorcraft oil filter

• You may fill up the new oil filter with fresh engine oil before installing it. This pace is optional, simply provides an extra layer of protection during startup post-obit an oil change. Lubricate the o-ring of the new oil filter with fresh engine oil, and then install it (of import step, the filter will not seal properly without a coat of oil on the black seal/gasket). Hand tighten the filter simply, do not employ a wrench.

Adding motor oil to the crankcase through the oil fill

• With the drain plug and new oil filter installed, fill the engine with fresh motor oil through the oil make full. Use a funnel to minimize spilling. Reinstall the oil fill cap and start the engine, making sure that engine oil pressure rises to normal inside a few seconds. With the engine running, cheque for leaks. With the engine off and absurd, check the oil level via the dipstick (rider side) to verify that the proper amount has been added to the crankcase.
