I've been away from the oil forums for a while, and am not as well read as I used to be. In any case, I've spent an hour searching and haven't seen anyone with a really high mileage 4.0 SOHC Ford engine to compare with. This is the first high mileage engine I've owned that has a fake oil...

So, I have a sort of partially restored 1965 black bomber, actually a particularly early one at serial number 1657. Cast into the alumnimum case, it says to use 30wt over 50 degrees, and 20 weight below, and that the oil capacity is 2.3L. It seemsly like everyone runs a thicker oil in vinatge...

My roommate's dad frimly believe the old urban myth about FRAM+Valvoline=good, Pennzoil=sludge. He has enough of a mechanical and science backround that he's willing to listen and learn, so I want to at least try to convince him that oil and filters have changed in the last 40 years. A. I know...

So, I inherited an older Craftsman (MTD looking) lawntractor for free the other day. Its a 11 HP briggs model with a 36" deck and a 4 speed manual transaxle. After maybe 3 years of year round outside storage, the transaxle would not shift out of 3rd gear, so I pulled it out and tore it apart to...

So, my local wal-mart just did a massive oil sale, and I walked out with quite a bit, including all 9 gallons of Delo 400 15W40 at $3/gallon. The question know is what to do with it! Would there be anything wrong with throwing a quart of M1 0W20 in with a gallon to drop the viscosity a tad...

Over thanksgiving I wound up a bit low on oil while traveling, and couldn't find any M1 5W40 to top up with. After checked the 4 or 5 places, I just bought M1 0W40 and used it, but I had plenty of time to think about the topic while driving back home today: 1. I know that all of the passenger...

Way back in the summer, I was asking questions here about what the best Non-Detergent oil would be for a 1948 Allis-Chalmers “G”. I had Blackstone do an analysis on the oil I changed out with the following results: Aluminum 8 Chromium 0 Iron 87 Copper 43 Lead 236 Tin 5 Molybdenum 1 Nickel 0...

A good friend of mine called me up yesterday afternoon from his cell phone, while standing in the oil isle of a Clark gas station. He was trying to find straight 30wt for his new (5 hour) Briggs engined lawnmower. Anyway, I told him that if they didn't have straight 30wt, 10W30 would work, but...

Friend's 1993 Saturn (DOHC) has been on cheap 10W40 dino for all of its 150k miles. This summer, he asked whether his dad's insistance on 10W40 was a good idea since the engine specs 5W30 on the filler. So, for the summer, I had him use Delvac 15W40 to sort of put off any major changes in...

I know this has been discussed before, but the search feature seems partially broken tonight. About half of the topics shown in each search apparently don't exist??!!?? Anyway, I know that Auto Rx is supposed to work best with base oils that have no esters. So, the real synthetics, and some of...

Ok, my 85+ year old grandmother religiously mows her yard with a pair of ~20 year old LawnBoys (she had a new one for about a week, then traded it back as she hated the kill switch, safety skirt, and starter rope location). She's probably mowing ~2 acres, and she really works at it, probably...

Ok, I've been using the Napa 1101 (Gard) on my Allis-Chalmers G tractor. Locally, I have a choice between it, and the Wix 51101, which uses a paper media per their web page The Napa filters, at least the ones that I'v bought before, used what appeared to be cotton waste as the media. Which...

On another forum, I've been seeing a lot of reccomendationst to remove the oil cooler entirely on 4.3 S-10's. Those that have done this beleive that the cooler is totally unnecessary because the full sized trucks with 4.3 don't have one. Also, a number of people claim that they have placed a...

Sorry if this has already been covered, or this is in the wrong section, but I couldn't find anything useful from searching: I have a 1948 Alis-Chalmers G tractor, with relatively low hours, used for Lawn and garden stuff by my family since new. It specs for 30 Weight oil for most conditions...

Subject says it all...my local Meijers is running sales on all of the Castrol products, and they have the price on the Blend 15W40 all the way down to $1/Qt! I had never even noticed it before, and the bottle doesn't give much info as to ratings...I think it was SL and CH-4, but it didn't list...

Ok, Meijer's is running a $1 off any purolator filter sale, which puts the Premium Plus at $1.99. For the applications that I usually by SuperTech's for (PF-52 and PF-25 equivalents) is there any advantage to the Purolator Premium Plus? For that matter, while the sale lasts, is it easier to...

Some beginner questions: My grandmother drives a 1966 Chevelle, which she bought new, and has only 78,000 miles. It is driven about 20-30 miles a week, in fairly short trips (7 miles). Her mechanic of many years has gone out of buisness, so I just put a SuperTech filter on it, and Chevron 10W30...

Before I knew better, I bought a 5qt jug of Syntec 10W30, which I finally decided to use up last oil change on my winter beater. Problem is that I happened to get a crappy SuperTech Filter with a Anti-drainback valve that didn't work (I got to watch the gauge stay on the peg way too long on each...
