Motor oil question

Would an SAE 30 API CF-2,CF,CC,CD diesel standards oil be suitable in the f-134?

The oils is maybe 8-10 years old. Stored inside at room temperature. There are no gasoline engine S codes but the CC says:

CC - Diesel Engine Service (Obsolete) - Service typical of certain naturally aspirated, turbocharged or supercharged diesel engines operated in moderate to severe-duty service, and certain heavy-duty gasoline engines. Oils designed for this service provide protection from bearing corrosion, rust, corrosion and from high to low temperature deposits in gasoline engines. They were introduced in 1961.

I can get quite a deal on a couple of buckets of it...

Thanx in advance...

For the $20 or so a gallon that quality lube oil (ie, Rotella) costs, I would never use the oil you describe in my CJ. Might be good as gold, but why chance it? Good, fresh, clean lube oil may not be the cure for everything, but lack thereof sure can cause a bucket of trouble.

 

heres some info i found.


Here is some info on oils and the API rating. Basically new oils are backwards compatible. Old spec oil is not good for newer engines. The oil you got is good for 2001 and older gasoline engines or 1994 and older Diesels.

Here is what the API ratings means. For starts, the "C" specification is for diesel (compression ignition) and the "S" series is for gasoline (spark ignition). Within each category is a series of specifications like CC, CD, CE, CF, CG, CH, SG, SH, SJ, etc. Look at the API (http://www.api.org/)website for better info. If you just want the medium length version this info below may help

GASOLINE ENGINES
SM Current. For all automotive engines currently in use. Introduced in 2004, SM oils are designed to provide improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil. Some SM oils may also meet the latest ILSAC specification and/or qualify as Energy Conserving.

SL Current. For 2004 and older automotive engines.
SJ Current For 2001 and older automotive engines.
SH Obsolete For 1996 and older engines.
SG Obsolete For 1993 and older engines.
SF Obsolete For 1988 and older engines.
SE Obsolete CAUTION: Not suitable for use in gasoline-powered automotive engines built after 1979. CAUTION: Not suitable for use in gasoline-powered automotive engines built after 1971. Use in more modern engines may cause unsatisfactory performance or equipment harm.

SD Obsolete. CAUTION: Not suitable for use in gasoline-powered automotive engines built after 1967. Use in more modern engines may cause unsatisfactory performance or equipment harm.

SC Obsolete. CAUTION: Not suitable for use in gasoline-powered automotive engines built after 1951. Use in more modern engines may cause unsatisfactory performance or equipment harm.
SB Obsolete
SA Obsolete CAUTION: Contains no additives. Not suitable for use in gasoline-powered automotive engines built after 1930. Use in more modern engines may cause unsatisfactory performance or equipment harm.

diesel engine
CJ4. Introduced in 2006. For high-speed, four-stroke engines designed to meet 2007 model year on-highway exhaust emission standards. CJ-4 oils are compounded for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval. CJ-4 oils are effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. Optimum protection is provided for control of catalystpoisoning, particulate filter blocking, engine wear, piston deposits, low- and high-temperature stability, soothandling properties, oxidative thickening, foaming, and viscosity loss due to shear. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.


CI-4 . Current. Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards implemented in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, CG-4, and CH-4 oils. Some CI-4 oils may also qualify for the CI-4 PLUS
designation.

CH-4 Current. Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards. CH-4 oils are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, and CG-4 oils.

CG-4 Obsolete. Introduced in 1995. For severe duty, high-speed, our-stroke engines using fuel with less than 0.5% weight sulfur. CG-4 oils are required for engines meeting 1994 emission standards. Can be used in place of CD, CE,
and CF-4 oils.

CF-4 Obsolete. Introduced in 1990. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CD and CE oils.

CF-2 Current. Introduced in 1994. For severe duty, two-stroke-cycle engines. Can be used in place of CD-II oils.

CF Current. Introduced in 1994. For off-road, indirect-injected and other diesel engines including those using fuel with over 0.5% weight sulfur. Can be used in place of CD oils.

CE Obsolete. Introduced in 1985. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CC and CD oils.
CD-II Obsolete. Introduced in 1985. For two-stroke cycle engines.
CD Obsolete. Introduced in 1955. For certain naturally aspirated and turbocharged engines.
CC Obsolete. CAUTION: Not suitable for use in diesel-powered engines built after 1990.
CB. Obsolete. CAUTION: Not suitable for use in diesel-powered engines built after 1961.
CA. Obsolete. CAUTION: Not suitable for use in diesel-powered engines built after 1959.

 

FWIW, I use 20W-50 in my L134. I use it for a couple of reasons. 1) it contains ZDDP which older flat tappet cams need to prevent premature wear 2) maintains good oil pressure when hot and 3) easier starting.

 

my hotrod guru told me to run the same thing in the f134

 

Thanx for the replies... I went with it. I'm pretty sure I'll be OK. Price was to good to let go...

Thanx

I too would suggest 20W50 Rotella or Delo or similar, rather than an old and obsolete grade oil. One additional advantage of the diesel oils is their very high detergent content. They are certified for gasoline engines too.

Valvoline Racing Oil is another good choice for flat tappet, emissions-exempt vehicles.

All of the replies told you not to buy the old oil. Apparently you didn't want advice - you wanted validation. :?

 

Actually, no, I wanted to know if an SAE 30 diesel engine oil with those API codes was suitable in my f-134. I read the replies and advice, which I appreciated people making, and made a decision.

I'm not sure why you would have me put such a heavy weight oil in my engine. I don't think I mentioned any oil pressure, hard starting, or other issues that would require it. I use, and wanted, an SAE 30, hence my question, which the answer to, I now know, is yes I can. While the age of the oil will require me to change my oil more regularly, that is not an issue in a vehicle that clocks maybe 2k a year. It gets changed twice in that time anyway.

 

Multi-vis oil is just that - multiple viscosity. At low temperatures it has the viscosity of 20W single grade, and at high temperatures it behaves like 50W. A 20W50 would be fine in all but the coldest climates. (Almost) nobody except racers use single grade oil now, because the multi-vis simply works better.

I expect that the valve spring pressure of an F134 is fairly low, and you don't need to worry so much about the ZDDP issue with modern oils. With a very high piston speed due to the long stroke, I expect the primary issue is maintaining an oil film in the rod bearings. The integrity of the oil film is directly related to oil pressure and oil viscosity. 20W50 seems like the way to go...

The CF-2 oil is an obsolete oil. Even my air compressor calls for 30W synthetic oil. My lawn mower calls for 10W30. Better oils are available - why not use them?
