Not what KIND of oil, but what VISCOSITY IS IT?

[page62]

Engine oil viscosity. Some also call it weight or grade. I'm curious what engine oil weight you use in your small six...10w30? 20w50? Straight 30? 15w40?

I don't care if you use Benny's Motor Oil, Castrol GTX, Amsoil, Mobil 1, or whatever Jiffy Lube sticks in your car. I'm just curious about what viscosity you choose, and why...

10W-30 valvoline racing oil. This oil & other racing oils contain ZZDT the anti-scuff additive so the camshaft & distributors gear live.

If you use another brand oil you need the ZZDT additive from comp cams or schneider cams. GM EOS also uses this additive.

Thats right if you use mobil 1 it does not contain this anti scuff additive.

Why use thicker oil, it robs HP, unless you have an oil burner.

I was using Mobil 1 full synthetic, 10W-30. Enough of it seeped around the head gasket that I wouldn't consider the 5W-20 or 30. If I drove mine in the Winter, I might consider 5W-20.

I am now using Motorcraft 10W-30 Synthetic Blend. Most of my Mustang driving is highways on road trips.

10w40

 

[JackFish]

10/30 in the summer 5/30 in the winter, since we see -40 up here.

I go by the original book. For the Mustang I use regular 10w40. Same for my Cadillac that I just spent a crap load of money on rebuilding. I for the most part stick with my 'family brand' but lately have been switching around rather than driving all over town to find the weight I am looking for in my brand. I also think that now days brand names mean much less than they did in the past because so many have combined and many have been bought by others and all that remains is the name. I dont feel I need any other weights because the engines are not any tighter than original specs. I have never felt any difference in performance or mileage changing weights or running synthetic. I dont think there is anything wrong with synthetic. I think they are very good in extreme conditions. I dont think I run most of my stuff in extremes so I just dont bother. I have been running a blend or full synth during the winter in my dd. Same opinion on all the zinc stuff. In extremes it may be needed but I have never seen any proof that fairly stock motor needs it.

ZDDP, you mean. Anyhow, I run Rotella/Delo 10W-30 because it still has more ZDDP than regular oil. Plus it's cheap.

 

[wsa111]

Thanks, i got to many ZZZ's.
Rotella still has some of the additive, but i heard they were cutting down on that to.
I did not know they offer 10w-30, i thought they had 15w-40 only.
Thanks for the info. Bill

Whoops, I was mistaken. It is 15-40. 15-40 shears down into 10-30 range anyhow, so it makes little difference.

I thought about trying the single-weight oil. The car never sees temperatures below 65* anyhow, so any benefit to a multigrade would be lost.

 

[fordconvert]

The rotella is made in several weights. I have seen it in 5-30 10-30 10-40 along with the more common 15-40. I think you only see 15-40 because thats a very common weight for diesels. Napa's in my area are the most common places I have seen the other weights.

THIS is the oil you NEED. ESPECIALLY with our old Inline sixers. It has ZINC which is CRITICAL in lubricating our cams and lifters. NOT EVEN ROTELLA has anywhere close to the amount of ZINC that it once did. AND NO OTHER OIL ON THE SHELF STILL HAS ANY ZINC. They also sell an addative that will give you ALL the ZINC you need to ADD to your Favorite brand of oil. CHECK IT OUT THOUGH, TOTALLY worth the time.

Yep, that or GM's EOS. STP is supposed to have ZDDP as well.

Read a bit at http://www.bobistheoilguy.com/forums/ubbthreads.php for good discussion on oils and additives.


The most recent analysis of Delo that I found still has over 1200 ppm ZDDP...that is plenty, and more than the amount found in the older car oil formulations.

For that matter, so did the Super Tech/Tech 2000 oil they tested.

 

[LaGrasta]

10w-40.
Kragen usually has Chevron or Havoline on sale from time to time for about 50¢/quart after rebate. Yes, i said 50¢! I usually buy multiple cases.

 

[48fordnut]

20w -50. cheap wal mart brand, super tech. Race engs to lawn mower.

 

[Harte3]

5w-30 Super Tech. Mostly driven in the winter when my "daily driver" is parked.

I use 10-30 full synthetic Mobile 1. I had been using Valvoline synthetic. I switched and immediately noticed the engine ran quieter! Same with the 3.8 in the wifes 98 Mustang. I have considered 10-40, but I buy mine 1 quart at a time every Friday at the Miejers while grocery shopping (It takes five weeks to get enough for a change, but it keeps me from feeling robbed at over $6 per quart). Having two cars to keep oil changes in it makes this a never ending process. They don't stock the 40 weight so I use the 30.

I too notice that full synthetic oil seems to leak everywhere. Even with the Fel Pro rubber valve cover gasket, I experiance slight seepage during long trips. Especially around (or maybe through) the breather. I get under it and over it looking for a specific leak, but there ain't any. The new head gasket doesn't leak at all, and the header doesn't get oil on it. But,what does seep results in a quarter sized drip on the driveway every few days, larger after a hard drive. I just get out a "VIVA" paper towel and wipe everything down. Any time you look under the engine it there is a drip hanging from the tranny pan, or the oil plug, or the front cross member. I just wipe it off. I loose about 1 quart in 5000 miles. Hell, BITD I lost that much just driving around, so I'm not too concerned.

That is a band. From wikipedia:

Motörhead are a British heavy metal band formed in 1975 by bassist, singer and songwriter Lemmy, who has remained the sole constant member. Usually a power trio, Motörhead had particular success in the early 1980s with several successful singles in the UK Top 40 chart. The albums Overkill, its follow on, Bomber, Ace of Spades, and particularly No Sleep 'til Hammersmith, cemented Motörhead's reputation as one of Britain's foremost heavy metal groups.[1] More recent exposure has included providing wrestler Triple H's entrance music, performing live at WrestleMania events, and in 2005 receiving their first Grammy.

While Motörhead are typically classified as heavy metal, speed metal or thrash metal (and often regarded as a foundational influence on the latter two styles),[2] Lemmy dislikes such labels, preferring to describe the band's music simply as "rock n' roll".[3] Motörhead's approach has remained the same over the band's career, preferring to play what they enjoy and do best; their appreciation of early rock and roll is reflected in some of their occasional cover songs. Motörhead's lyrics typically cover such topics as war, good versus evil, abuse of power, promiscuous sex, substance abuse, and "life on the road." The band's distinctive fanged-face logo, Snaggletooth, with its oversized boars' horns, chains, and spikes, was created by artist Joe Petagno in 1977 for the cover of the Motörhead album and has appeared in many variations on covers of ensuing albums.
