Hello all,
This thread is not intended as a discussion, just taking a poll:

• What type of oil is in your X-type right now?
• What oil filter?

Thanks

 

If I remember right, I have Castol GTX (5W-30) in the car with a Fram XtraGuard filter. But, I also known to use Havoline, Mobil 1, and Penzoil (all 5W-30). I tend to find what the local store is having on sale and go with that. Haven't noticed any difference between the brands and even tried a full synthetic and a blend. My mileage didn't shift between the different types. Others have had a different experience.

 

Valvoline max life full synthetic 5w-30 with a k&n wrench off filter.

2100 miles on the oil change and it still looks clean as new.

Dexos 5W-30 Synthetic w/ Chemlube oil filter - We use Express Lube synthetic services.

Expect to change oil every 5k miles.

 

Just put that in my car today too

 

I have Castol GTX (5W-30) and a Fram XtraGuard filter. They went on sale this month at AutoZone.

 

Mobil 1 (extended performance) 5w30 with Mobil 1 oil filter
I did try slick 50 with my oil change prior to this one with castrol GTX not sure i had any gains but she feels smother with the mobil 1 and i have gained 2MPG on my trip computer average before was 24 now getting 26 on the highway I reset on every gas fill up.

 

Amsoil 5w30 synthetic, Fram filter.


Oil that was in there came back from the lab as generic dino oil, 5w30, no obvious signs of engine wear. Seems likely, since the previous owner used a bulk shop to do the changes every 3K like clockwork.


I figure the Amsoil should give me a year (5k or so), but I'll send a lab sample out every 3 months or so to see what it does.

 

Motorcraft Semi Synthetic 5w20 and motorcraft filter. Was on sale - get a free filter with 5 qts or a jug ( $24.99+tax ). I use the same stuff but in 5w30 for my Excursion ( v10 ) and it's worked fine.

Valvoline dino oil

 

i use the cheapest one on the shelf




i have a daily driver saturn i use for work witch has 270,000 miles on it with what ever oil i find to put in it ,every 5000 , i do the same with my jag, my father used to work at british leyland and tested oil and told me put what evers cheapest and just change it every 5000,so i followed his advice and had sucess with all my cars without the added expense of overpriced oil

 

Currently Penzoil 5W-30 Synthetic. Next oil change soon will be either Amzoil 5W-30 OE synthetic or Castrol Syntec. Oil Changes at 10,000 kilometres (about 6,200 miles). No oil loss between changes. I thought Synthetic was recommended because of the long change intervals but I see many people using conventional oil? Any difference is fuel economy? I may run conventional in the summer and do a change again in October. Because I really need synthetic for our extremely cold winters. Then again a case of 6 synthetic bottles of Castrol is like $35 @ Costco which isn't bad for Canada.

valvoline synpower 5w30 but soon to be a little thicker as it is now starting to loose about a quart and a half every 6 months.

 

trugr8ns, in my case, when I used the blended oil and the full synthetic oil, I did not see a change in my mileage even though I was driving very similarly. Other people have had good results. May have to give it a try and see what you experience.

 

My goodness- 17 replies to an oil post and no fights. Congrats!

Conventional or synthetic?
