Witch engine oil is suitable for a VW Jetta 4?


TWO answers read and follow the Manufacturers Specification. OR Always use ** 15-40 Diesel Rated Oil is ALL gas, natural/propane and diesel Engines! Use Purolator, then WIX, then Manufacturers Filters - NEVER Fram, "special". oil the oil lube shops filters!!! WHY? When flying planes, every 100 hours I remove the filter, cut it open, and INSPECT the filter material for particulate. My Vehicle Engines go for well over 600,000 miles - most other peoples. simply do NOT!

** I use Delo 15-40 in everything - an better one is Shell Rotunda, however too expensive and not needed! In gas engines after 500 miles, the FIRST Time ONLY - Replace the oil AND FILTER - mixed fuels and oils NEVER mix well. Then on gas engines ONLY replace the filter at the "normal" intervals and ADD not change, the oil... On Diesels, due to the extreme compression, you DO change the oil, at "normal" intervals. In gas, NOT diesel engines - you could use Pep Boys and/or Walmart's generic DIESEL GRADE oil - NOT in diesel engines, as from my experience.

AVOID gasohol - unless you like flash rust and oxidation inside your engine AND 30% less fuel mileage - NEVER use WD40 on ANY metal you want to reuse! And do NOT use BP or unknown small time gas stations - as MANY "top off their fuels" with other octanes - which LOWERS the octane - do to "covalent bonding of carbon molecules" Example: a 50/50 mix of 100 octane with 90 = closer to 80 NOT "in the middle".

What is the gas oil mix ratio for a model 9400sx shark Eskimo ice auger?


50:1 Is what find list in other forums. Your best is use a good multi mix oil that you don't getting the mix perfect. These oil are usually good form 16:1 to 50:1. Here I use one gallon mix bottle and mix one gallon of fuel at a time for all my two cycle chainsaws and trimmers.

How many ounces of oil do I add to gasoline to get a 50 to 1 mix?


Quite simple if the mix says 1:50 ( one to 50 ) ,it means for every one ounce of oil you add 50 ounces of gasoline.

If the instructions say 1/50 ( one of 50 parts) ,it means for every let us say 50 ounces of mix there are 49 ounces of gas and one ounce of oil.I use a one liter wine bottle !000 ml ,I put in 20 ml of oil fill bottle with gas and shake well-ps (mark bottle -hate to take a swig).If you are into avoirdupois system use 1 ounce oil add 50 ounces fresh gas .

My husqy 435 runs but skips and bogs when you give it gas! spark plug is good, air filter is clean. could it be the ignition pack?


It could be the ignition module, but if since it is firing I would say it is a bad fuel filter. Try replacing it. Also, try using fresh gas. Mix a 50/50 gas to engine oil mixture and put that in.

How much gas to mix the oil in?


First check that your Mantis needs an oil/gas mixture, most of the newer Mantis tillers have four-stroke motors meaning they have oil in the crankcase and use straight gas. If your Mantis needs oil mixed in the gas use a 50:1 ratio. That's usually 2.6 ounces of two-cycle oil (it's sold in bottles that size) to one gallon of gas but read the oil bottle to get the proper mix ratio.

Having problems starting Makita strimmer. There is quite a lot of smoke coming out and then it stops. Have looked at spark plug -clean, and cleaned air filter. Could the problem be the petrol and oil mix.


Use 50:1 gas/oil with a GOOD QUALITY 2-cycle low-ash synthetic oil.

Remove the muffler and check the spark arrestor isn't partially blocked.

With a clear muffler, and the mix as described, there will be hardly any smoke at all.

What type of fuel mixture do I use for 20760 Homelite gas trimmer?


Most likely not the answer you are looking for but here is a shot:

Pick up a bottle of the Echo brand 2-cycle oil. It will say "Extended Life" on the labeling. This is meant to run in Echo products, but it is a very FINE and well engineered oil. Mix it according to label directions for 50:1 ratios. (2.6 Oz. to 1 Gal. Gasoline)

When mixed at this ratio it provides MORE than adequate engine protection for ALL 2-Cycle engines, including those that run in 40, and 30:1 ratios.

I mix one 2-cycle tank to label instructions on the Echo oil for 50:1. It handily runs in my Echo chainsaws, non-echo trimmer, Poulan Pro leaf blower, etc. They all run different ratios, but THRIVE on the Echo mix without as much oily residue and smoke to boot!

CAUTION: I do not know of ANY OTHER MAKE of 2-cycle oil that CAN DO THIS *SAFELY*.

Remember:

Always mix your 2-cycle fuel starting with *fresh* gas.

Mix only that which you can use in 30 days.

Use 89 Octane fuel to make your mix in small piston 2-cycle engines.

Clean and re-oil intake filters @ every 10 hrs. operation time. Check and re-gap your plug when you service your filter!

DRAIN unused fuel from tank back into gas mix container. Restart and let engine idle to run any remaining fuel out of engine and carb. Storing fuel in ANY 2-cycle longer than two weeks is going to gum them up and nothing short of a carb rebuild will get them sputtering back to life again!

Need to know gas mixture


Yours is not a current model and I did not find a manual. The following is an excerpt from a 26cc MightyLite Blower/Vac UT08550/UT08951 "Operator's Manual":
This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean 1 gallon container approved for gasoline.
Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use.
Mix Homelite Premium Exact Mix lubricant with gasoline according to the instructions on the package. If Premium Exact Mix lubricant is not available, use a high quality synthetic 2-cycle engine lubricant, mixed at 2.6 oz. per gallon (US).
Do not use automotive lubricant or 2-cycle outboard lubricant.
NOTE: Premium Exact Mix fuel mix will stay fresh up to 30 days. DO NOT mix quantities larger than usable in a 30 day period.
PREMIUM EXACT MIX (50:1)
GasolineLubricant
1 gallon (US) 2.6 oz.
1 Liter 20 cc (20 ml)

If properly adjusted your blower will operate fine on 50:1 regardles of what the manual reads. HTH
