what oil

[interceptor1985]

I use castrol GTX and Lucas oil for the gears and I havent had to put oil in the tranny yet....Does castrol make tranny oil for automatics? And I stay far far away from fram products

that just means your filter isnt filtering as efficiently as the old filter. once it starts filtering the smaller particles the pressure will drop.

My oil pressure doesn't drop between oil changes. My filter doesn't get plugged, as I change my oil every 2000 miles. The 4-5 pounds I see is a result of internal differences in the filter.

Today I bought a case of Mobil-1 for the first time. Just gotta decide now whether to just get a Purolator or similar filter or call up a shop I know that peddles Amsoil products. I must have bigger clearances than some folks, because my engine really hasn't been entirely happy on the 5W30 Motorcraft synthetic blend.

If you're gonna drop the coin for Mobil-1, you may as well make sure you get a filter that's gonna let the oil live up to its full potential. Spring for the amsoil. Also, amsoil products can be purchased online, and their shipping is really fast for me. Sometimes it's here the next day, but it's usually only two days at most.

BTW, what grade Mobil-1 did you buy? My car is happy as a clam on 10W30, but I'd imagine I don't have a ton of wear, I've been running synthetic of some kind in it since it had about 30k on it...now at 142k.

I got 10W30 also ... this engine is about two years old, but hey, it's noisy enough anyway, so I'll give it what it wants!

I assume I'd be looking at about $15 for a filter from Amsoil? Do they have different filters available like their different varieties of oils?

Edit: Website's showing $18.10 for the EaO, $6.55 for the WIX, and $11.95 for the WIX Racing. I notice Mobil-1 filters are supposed to be good as well for apparently around $10 each .... don't remember offhand who sells them, though.

Royal Purple oil and Wix filters

That is exactly what I run.

I use RP in everything, From my Diesel truck, to the race car, to the stang.....

I even have my parents using RP in their cars, shit, even my grandpa uses it.


In my truck I have RP in the motor, trans, transfercase, rear, and front gear.

Same deal with the racecar. RP in the motor, trans, and rear......

We use Castrol GTX for the Mk1 Capri's and Lucas for the 4 speed tranny and the rear gears. Does Lucas or Castrol Make tranny fluid that I could use in my 1999?

Here's my recipe:
EaO Filters
Supertech 10W30 Full synthetic
Oil changes every 6.5k

That's what I run in the box, and that's what I run in the highspeed suppository (1998 dodge grand caravan, 3.8 liter, 235k, uses no oil between 6.5k changes) my dad and I have run that recipe though it since it was new.

Just get a Mobil1 or a K&N oil filter. AutoZone sells both.

I have recently switched to using Valvoline MaxLife 10w40 with a K&N oil filter in the Deuce. I run Castrol GTX High Mileage 5w30 with a Mobil1 filter in the Beretta.

I also run Castrol GTX 5w30 with a Bosch filter in the lady's Civic.

Castrol and Valvoline are the way to go. No Pennzoil, no Quaker State, no off brand. The cheapest filter I will use on any vehicle is the Bosch Premium oil filter. No STP, no Fram, no off brand.

Look inside of the different filters and compare the build too. Never buy STP, because most of the filters I have seen have nothing holding back the filter on it, except maybe a plastic liner. Same thing with the SuperTech filters. When you look in them, you can see the WHOLE filter element. And Fram, VERY thin cheaply made filtering element. It's known for falling apart over time.

Remember, YOU GET WHAT YOU PAY FOR.

OK, just put in 5 quarts of Mobil-1 10W30 and a Carquest oil filter. The car seems to really like it so far - very smooth and quiet as this car goes.

What sort of oil change intervals do you mangs observe with the mid-priced full-synth oils? The Mobil-1 is pricey for my tastes, but appears to be less than half the price of Amsoil .... I just hate to change it twice a year like with dino juice if it's not needed.

The Carquest filter is supposed to be made by Wix, which is good ... but to be more certain I talked to a guy at a NAPA that said it sold Amsoil products also. He told me the NAPA Gold is identical to the "real" Wix filter and the Silver is a different design made for them by Wix, and additionally that the last Amsoil filter he got in appeared to be identical to the Wix filters he already stocks, so now he just recommends NAPA Golds to anyone wanting a really good filter and only bugs Amsoil for their oils. I don't know if the Carquest filter I have is the same or not, but I'm thinking next time I'll just buy a NAPA Gold and call it good!

Huh. How much are the NAPA Gold filters compared to Amsoil? I'd certainly be interested if anybody cut one open and did a comparison.

[1987cp]

napaonline.com is showing $5.69 each for the NAPA Gold 1515. Amsoil.com wants $6.55 for a Wix 51515 and $18.10 for the Amsoil EAO15. Does seem like a big price difference if they're actually the same .....

I wouldnt get the wix racing filter for a stock car, I have 2 of them in the garage, but I dont even really want to run them on my race car.

It says right on the box that they come in not intended for street use. I think the main problem with the wix racing filter is that it is a full flow filter and that it doesnt filter as well as a wix gold......
thats my .02

But if any one is interested in them, i will send 2 of them out for $25 shipped.....
